# For maximal compatibility with older versions, we Use "ocamlc -v"
# instead of "ocamlc -vnum" or the VERSION file in .../lib/ocaml/.
# This script extracts the components from an OCaml version number
# and provides them as C defines:
# OCAML_VERSION_MAJOR: the major version number
# OCAML_VERSION_MAJOR: the minor version number
# OCAML_VERSION_PATCHLEVEL: the patchlevel number if present, or 0 if absent
# OCAML_VERSION_ADDITIONAL: this is defined only if the additional-info
# field is present, and is a string that contains that field.
# Note that additional-info is always absent in officially-released
# versions of OCaml.
