# Parse the NASM version file and produce appropriate macros
#
# The NASM version number is assumed to consist of:
#
# <major>.<minor>[.<subminor>]<tail>
#
# ... where <tail> is not necessarily numeric.
#
# This defines the following macros:
#
# version.h:
# NASM_MAJOR_VER
# NASM_MINOR_VER
# NASM_SUBMINOR_VER -- this is zero if no subminor
# NASM_VER -- whole version number as a string
#
# version.mac:
# __NASM_MAJOR__
# __NASM_MINOR__
# __NASM_SUBMINOR__
# __NASM_VER__
