#ifndef BOOST_REGEX_CONFIG_HPP
#define BOOST_REGEX_CONFIG_HPP
/************************************************************************
The purpose of this header is to provide compiler and STL configuration
options. Options fall into three categaries (namespaces, compiler and STL),
throughout, the defaults assume that the compiler and STL are fully C++ standard
compliant, features that are not supported on your system may be selectively
turned off by defining the appropriate macros. Borland C++, Borland C++ Builder,
and Microsoft Visual C++ should be auto-recognised and configured. The HP aCC and
SunPro C++ compiler should also be supported - but run configure for best results.
The SGI, HP, Microsoft and Rogue Wave STL's should be auto-recognised and configured.
Do not change this file unless you really really have to, add options to
<boost/regex/detail/regex_options.hpp> instead. See <regex_options.hpp> for a
full list of macros and their usage.
