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", "nvhpc" (NVIDIA HPC +# Compiler), "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.
