the aCC compiler.
dit(bf(CCACHE_STRIPC)) If you set the environment variable
CCACHE_STRIPC then ccache will strip the -c option when invoking
the preprocessor. This option is primarily for the Sun Workshop
C++ compiler as without this option an unwarranted warning is displayed:
CC: Warning: "-E" redefines product from "object" to "source (stdout)"
when -E and -c is used together.
dit(bf(CCACHE_SWIG)) When using SWIG as the compiler and it does not
have 'swig' in the executable name, then the CCACHE_SWIG environment
variable needs to be set in order for ccache to work correctly with
