[mpich-discuss] mpich2 compilation with intel only

[Dave Goodell]

Looks like your intel compiler is broken somehow when compiling under "-no-gcc".  The "icc" compiler is finding the system-installed, gcc-specific stdarg.h which is blowing up with a "__MWERKS_" error message.  My guess is that it won't complain if you drop "-no-gcc" because this will cause icc to #define "__GNUC__" and similar symbols that will make the system header happier.

Are you *sure* that the "-no-gcc" option is what you want?  Will it compile simple C programs that "#include <stdarg.h>" without any involvement with MPICH2?
