Fix BOOST_MPL_AUX_ASSERT_NOT_NA

Do not check the birand/bitor macros in cplusplus mode
Some 3rdparty parsers (e.g. Qt moc) fail to parse the bitand.hpp due to the fact that bitand is a keyword in C++, not a macro. Modern MSVC versions define bitand/bitor only if __cplusplus macro is not defined, see iso646.h: https://pastebin.com/zTcd0juT Thus, boost can also check the macro only in C mode making moc happy

+# Generic Appveyor build script for boostorg repositories
+# See: https://github.com/boostorg/boost-ci/
+#
+# Instructions for customizing this script for your library:
+#
+# 1. Customize the compilers and language levels you want.
+# 2. If you have more than include/, src/, test/, example/, examples/,
+#    benchmark/ or tools/ directories, set the environment variable DEPINST.
+#    For example if your build uses code in "bench/" and "fog/" directories:
+#      - DEPINST: --include bench --include fog
+# 3. Enable pull request builds in your boostorg/<library> account.
+#
+# That's it - the script will do everything else for you.

-# Generic Travis CI build script for boostorg repositories
-# See: https://github.com/jeking3/boost-ci
-#
-# Instructions for customizing this script for your library:
-# 
-# 1. Customize the compilers and language levels you want in the 'jobs'.
-# 2. If you have more than include/, src/, test/, example/, examples/, or
-#    tools/ directories, modify your Travis CI project and add the environment
-#    variable DEPINST.  For example if your build uses code in "bench/" and
-#    "fog/" directories, then set DEPINST to the following:
-#        --include bench --include fog
-# 3. If you want to enable Coverity Scan, you need to provide the environment
-#    variables COVERITY_SCAN_TOKEN and COVERITY_SCAN_NOTIFICATION_EMAIL in
-#    your github settings.
-# 4. Enable pull request builds in your boostorg/<library> account.
-#
-# That's it - the scripts will do everything else for you.

-# Generic Appveyor build script for boostorg repositories
-# See: https://github.com/jeking3/boost-ci/
-#
-# Instructions for customizing this script for your library:
-#
-# 1. Customize the compilers and language levels you want.
-# 2. If you have move than include/, src/, test/, example/, examples/,
-#    benchmark/ or tools/ directories, set the environment variable DEPINST.
-#    For example if your build uses code in "bench/" and "fog/" directories:
-#      - DEPINST: --include bench --include fog
-# 3. Enable pull request builds in your boostorg/<library> account.
-#
-# That's it - the script will do everything else for you.

Ivan Komissarov	502078c91d	Do not check the birand/bitor macros in cplusplus mode Some 3rdparty parsers (e.g. Qt moc) fail to parse the bitand.hpp due to the fact that bitand is a keyword in C++, not a macro. Modern MSVC versions define bitand/bitor only if __cplusplus macro is not defined, see iso646.h: https://pastebin.com/zTcd0juT Thus, boost can also check the macro only in C mode making moc happy	2025-01-03 11:34:47 -05:00
