Configuring make does the "checking if cpp works" thing and fails - boom,
build stops.

That's not the problem I saw in above case. It failed because some standard
header in /usr/include included <sys/cdefs.h>. Due to __GNUC__ not being
defined this hit the #error in line 232. There are no fixinclud-mangled
files involved here.

If you say that calling plain cpp(1) should not automagical define __GNUC__
we should fix our headers. Or make everything call "cc -E" (along the lines
of the xsrc changes quite some time ago). Or probably both.
