/* "4cpp" Open C++ Parser v0.1: String
no warranty implied; use at your own risk
NOTES ON USE:
OPTIONS:
Set options by defining macros before including this file
FCPP_STRING_IMPLEMENTATION - causes this file to output function implementations
- this option is unset after use so that future includes of this file
in the same unit do not continue to output implementations
FCPP_LINK - defines linkage of non-inline functions, defaults to static
FCPP_EXTERN changes FCPP_LINK default to extern, this option is ignored if FCPP_LINK is defined
include the file "4cpp_clear_config.h" if yo want to undefine all options for some reason
HIDDEN DEPENDENCIES:
none
