The vendor is 12# returned in the cache variable $ax_cv_c_compiler_vendor for C, 13# $ax_cv_cxx_compiler_vendor for C++ or $ax_cv_fc_compiler_vendor for 14# (modern) Fortran. The value is one of "intel", "ibm", "pathscale", 15# "clang" (LLVM), "cray", "fujitsu", "sdcc", "sx", "nvhpc" (NVIDIA HPC 16# Compiler), "portland" (PGI), "pcc", "gnu" (GCC), "sun" (Oracle Developer 17# Studio), "hp", "dec", "borland", "comeau", "kai", "lcc", "sgi", 18# "microsoft", "metrowerks", "watcom", "tcc" (Tiny CC) or "unknown" (if 19# the compiler cannot be determined). 20# 21# To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT 22# with an appropriate preprocessor-enabled extension. For example: 23# 24# AC_LANG_PUSH([Fortran]) 25# AC_PROG_FC 26# AC_FC_PP_SRCEXT([F]) 27# AX_COMPILER_VENDOR 28# AC_LANG_POP([Fortran]) 29# 30# LICENSE 31# 32# Copyright (c) 2008 Steven G.
