Determine the vendor of the C, C++ or Fortran compiler. The vendor is returned in the cache variable $ax_cv_c_compiler_vendor for C, $ax_cv_cxx_compiler_vendor for C++ or $ax_cv_fc_compiler_vendor for (modern) Fortran. The value is one of "intel", "ibm", "pathscale", "clang" (LLVM), "cray", "fujitsu", "sdcc", "sx", "portland" (PGI), "gnu" (GCC), "sun" (Oracle Developer Studio), "hp", "dec", "borland", "comeau", "kai", "lcc", "sgi", "microsoft", "metrowerks", "watcom", "tcc" (Tiny CC) or "unknown" (if the compiler cannot be determined).

To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT with an appropriate preprocessor-enabled extension. For example:
