#
# Parse the NASM version file and produce appropriate macros
#
# The NASM version number is assumed to consist of:
#
# <major>.<minor>[.<subminor>][pl<patchlevel>]]<tail>
#
# ... where <tail> is not necessarily numeric, but if it is of the form
# -<digits> it is assumed to be a snapshot release.
#
# This defines the following macros:
#
# version.h:
# NASM_MAJOR_VER
# NASM_MINOR_VER
# NASM_SUBMINOR_VER -- this is zero if no subminor
# NASM_PATCHLEVEL_VER -- this is zero is no patchlevel
# NASM_SNAPSHOT -- if snapshot
# NASM_VERSION_ID -- version number encoded
# NASM_VER -- whole version number as a string
#
# version.mac:
# __NASM_MAJOR__
# __NASM_MINOR__
# __NASM_SUBMINOR__
# __NASM_PATCHLEVEL__
# __NASM_SNAPSHOT__
# __NASM_VERSION_ID__
# __NASM_VER__
