this is from gcc-1.30:

there is a conditional in cccp.c that reads:
	if (out_fname && !strcmp(out_fname, ""))
this should be
	if (!out_fname || !strcmp(out_fname, ""))
otherwise gcc -E, or the use of cpp w/o an output file name will fail with the
message
cpp: Invalid argument for `'
on a machine w/o page 0 mapped out.
