 # DESCRIPTION
 #
-#   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", "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.  For example:
-#
-#     AC_LANG_PUSH([Fortran])
-#     AC_PROG_FC
-#     AC_FC_PP_SRCEXT([F])
-#     AX_COMPILER_VENDOR
-#     AC_LANG_POP([Fortran])
+#   Determine the vendor of the C/C++ compiler, e.g., gnu, intel, ibm, sun,
+#   hp, borland, comeau, dec, cray, kai, lcc, metrowerks, sgi, microsoft,
+#   watcom, etc. The vendor is returned in the cache variable
+#   $ax_cv_c_compiler_vendor for C and $ax_cv_cxx_compiler_vendor for C++.
