+// There are a few parameters that affect the macros defined in this file:
+//
+// - What version of CCE (Cray Compiling Environment) are we running? This
+//   comes from the '_RELEASE_MAJOR', '_RELEASE_MINOR', and
+//   '_RELEASE_PATCHLEVEL' macros.
+// - What C++ standards conformance level are we using (e.g. '-h
+//   std=c++14')? This comes from the '__cplusplus' macro.
+// - Are we using GCC extensions ('-h gnu' or '-h nognu')? If we have '-h
+//   gnu' then CCE emulates GCC, and the macros '__GNUC__',
+//   '__GNUC_MINOR__', and '__GNUC_PATCHLEVEL__' are defined.
+//
+// This file is organized as follows:
+//
+// - Verify that the combination of parameters listed above is supported.
+//   If we have an unsupported combination, we abort with '#error'.
+// - Establish baseline values for all Boost macros.
+// - Apply changes to the baseline macros based on compiler version. These
+//   changes are cummulative so each version section only describes the
+//   changes since the previous version.
+//   - Within each version section, we may also apply changes based on
+//     other parameters (i.e. C++ standards conformance level and GCC
+//     extensions).
+//
+// To test changes to this file:
+//
+// ```
+// module load cce/8.6.5 # Pick the version you want to test.
+// cd boost/libs/config/test/all
+// b2 -j 8 toolset=cray cxxstd=03 cxxstd=11 cxxstd=14 cxxstd-dialect=gnu linkflags=-lrt
+// ```
+// Note: Using 'cxxstd-dialect=iso' is not supported at this time (the
+// tests run, but many tests fail).
+//
+// Note: 'linkflags=-lrt' is needed in Cray Linux Environment. Otherwise
+// you get an 'undefined reference to clock_gettime' error.
+//
+// Note: If a test '*_fail.cpp' file compiles, but fails to run, then it is
+// reported as a defect. However, this is not actually a defect. This is an
+// area where the test system is somewhat broken. Tests that are failing
+// because of this problem are noted in the comments.
+//
+// Pay attention to the macro definitions for the macros you wish to
+// modify. For example, only macros categorized as compiler macros should
+// appear in this file; platform macros should not appear in this file.
+// Also, some macros have to be defined to specific values; it is not
+// always enough to define or undefine a macro.
+//
+// Macro definitions are available in the source code at:
+//
+// `boost/libs/config/doc/html/boost_config/boost_macro_reference.html`
+//
+// Macro definitions are also available online at:
+//
+// http://www.boost.org/doc/libs/master/libs/config/doc/html/boost_config/boost_macro_reference.html
+//
+// Typically, if you enable a feature, and the tests pass, then you have
+// nothing to worry about. However, it's sometimes hard to figure out if a
+// disabled feature needs to stay disabled. To get a list of disabled
+// features, run 'b2' in 'boost/libs/config/checks'. These are the macros
+// you should pay attention to (in addition to macros that cause test
+// failures).

-#if _RELEASE < 8
+// In a developer build of the Cray compiler (i.e. a compiler built by a
+// Cray employee), the release patch level is reported as "x". This gives
+// versions that look like e.g. "8.6.x".
+//
+// To accomplish this, the the Cray compiler preprocessor inserts:
+//
+// #define _RELEASE_PATCHLEVEL x
+//
+// If we are using a developer build of the compiler, we want to use the
+// configuration macros for the most recent patch level of the release. To
+// accomplish this, we'll pretend that _RELEASE_PATCHLEVEL is 99.
+//
+// However, it's difficult to detect if _RELEASE_PATCHLEVEL is x. We must
+// consider that the x will be expanded if x is defined as a macro
+// elsewhere. For example, imagine if someone put "-D x=3" on the command
+// line, and _RELEASE_PATCHLEVEL is x. Then _RELEASE_PATCHLEVEL would
+// expand to 3, and we could not distinguish it from an actual
+// _RELEASE_PATCHLEVEL of 3. This problem only affects developer builds; in
+// production builds, _RELEASE_PATCHLEVEL is always an integer.
+//
+// IMPORTANT: In developer builds, if x is defined as a macro, you will get
+// an incorrect configuration. The behavior in this case is undefined.
+//
+// Even if x is not defined, we have to use some trickery to detect if
+// _RELEASE_PATCHLEVEL is x. First we define BOOST_CRAY_x to some arbitrary
+// magic value, 9867657. Then we use BOOST_CRAY_APPEND to append the
+// expanded value of _RELEASE_PATCHLEVEL to the string "BOOST_CRAY_".
+//
+// - If _RELEASE_PATCHLEVEL is undefined, we get "BOOST_CRAY_".
+// - If _RELEASE_PATCHLEVEL is 5, we get "BOOST_CRAY_5".
+// - If _RELEASE_PATCHLEVEL is x (and x is not defined) we get
+//   "BOOST_CRAY_x":
+//
+// Then we check if BOOST_CRAY_x is equal to the output of
+// BOOST_CRAY_APPEND. In other words, the output of BOOST_CRAY_APPEND is
+// treated as a macro name, and expanded again. If we can safely assume
+// that BOOST_CRAY_ is not a macro defined as our magic number, and
+// BOOST_CRAY_5 is not a macro defined as our magic number, then the only
+// way the equality test can pass is if _RELEASE_PATCHLEVEL expands to x.
+//

+// compiler.
