When compiling wxGTK-2.6.3 with "gcc (GCC) 4.1.2 20060628 prerelease (NetBSD
nb1 20060602)", it fails with:

./include/wx/wxprec.h:1: internal compiler error: in pch_init, at c-pch.c:135
Please submit a full bug report,
with preprocessed source if appropriate.

In NetBSD GNATS #33820, Johan Wallén came up with a simpler test:
# echo 'extern int foo[8];' > /tmp/test.h
# c++ /tmp/test.h
/tmp/test.h:1: internal compiler error: in pch_init, at c-pch.c:135
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.netbsd.org/Misc/send-pr.html> for instructions.
# ll /tmp/test.h*

-rw-r--r--  1 tk  wheel   0 Jul  1 12:30 /tmp/test.h.gch

With "gcc version 4.2.0 20060615 (experimental)", the error is different:
cc1plus: warning: /tmp/test.h.gch: too short to be a PCH file
resulting in
-rw-rw-r--  1 mrg  wheel       19 Jul  1 03:29 /tmp/test.h

------- Comment #1 from tk at giga dot or dot at  2006-07-01 10:41 -------
mrg@NetBSD.org says it's a NetBSD problem, because NetBSD "does not use the
normal checksum stuff". Sorry for the bogus report.
