Doesn't seem that way:
556 $ gcc --version

#define MACRONAME @macroname@

However, in an arbitrary "makefile.in":
# $LynxId: makefile.in,v 1.118 2011/06/12 18:36:28 tom Exp $
##makefile for lynx
SHELL = @CONFIG_SHELL@
CDPATH = .
.SUFFIXES:
@SET_MAKE@
prefix = @prefix@
exec_prefix = @exec_prefix@
top_srcdir = @top_srcdir@
srcdir = @srcdir@
builddir = .
VPATH = $(srcdir)
These "@...@" are replaced when GNU configure filters makefile.in to makefile.
Did the OP bypass a configure step?
(I'd hate do do all that from JCL.)
Mr. Natural sez, Use the right tool for the job.
