# Usage: m4-ccas --m4=M4 CC ... file.asm ...
#
# Process file.asm with the given M4 plus any -D arguments, then
# assemble with the given CC plus all arguments.
#
# The M4
command must be in
a single --m4= argument, and will be split
# on whitespace. When CC is invoked file.asm is replaced with
a
# temporary .
s file which is the M4
output.
#
# To allow parallel builds, the temp file name is based on the .asm
# file name, which will be the
output object filename for all uses we
# put this
script to.
