GNOME 0.5.0 on AIX 4.3.2 and Digital Unix 4.0D compile fails

[allbery ece cmu edu]

gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I.. -I../../src -I/usr/local/lib/glib/include -I/usr/local/include -DORBit_SYSRC=\"/usr/local/etc/orbitrc\" -include /afs/.ece.cmu.edu/support/orbit/0.5.0/src/configure-hack.h -c  -DPIC interface_repository-stubs.c -o .libs/interface_repository-stubs.lo

(and on and on and on)

The list is a bit shorter on AIX but it's largely the same failure. 
And the file does indeed contain control characters, which look like
they were supposed to be tokens but didn't get expanded.

So, am I doing something idiotic?

Tried:  gcc 2.7.2.3 (shown), gcc 2.95.1 (same but 07 is more popular
than 0344).
Using /bin/ksh on DUX as per README (using /bin/sh has no effect).  No
special configure options.
