23# Usage: m4-ccas --m4=M4 CC ... file.asm ...
24#
25# Process file.asm with the given M4 plus any -D arguments, then
26# assemble with the given CC plus all arguments.
27#
28# The M4 command must be in a single --m4= argument, and will be split
29# on whitespace.  When CC is invoked file.asm is replaced with a
30# temporary .s file which is the M4 output.
31#
32# To allow parallel builds, the temp file name is based on the .asm
33# file name, which will be the output object filename for all uses we
34# put this script to.
