11 # Determine the vendor of the C, C++ or Fortran compiler. 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).
21 # To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT
22 # with an appropriate preprocessor-enabled extension. For example:
24 # AC_LANG_PUSH([Fortran])
26 # AC_FC_PP_SRCEXT([F])
28 # AC_LANG_POP([Fortran])
