CPPFLAGS...

[Ben Bergen]

If this is the wrong forum for this question, please let me know where
to send it.  I am working on a project that mixes C and C++.  The
problem that I have is that there is only one CPPFLAGS for both
compilers.  Why is this the case?  It would be nice if
automake/autoconf provided a CXXPPFLAGS variable so that the flags
could be set independently.  This is not a problem if you are only
using gcc with g++.  However, for performance reasons, I need to use
g++ with the IBM xlc compiler.  Does anyone have a work-around or
suggestion?  Is this something that could be changed in the autoconf
package???
