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), "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.
