OK, forget the comment about stdc-predef.h, I was looking in my GCC install
area instead of the glibc root area. I do have stdc-predef.h.
The failure mode is a refusal to use any precompiled headers. I.e. the first
line in the test program (common-1.c from gcc.dg/pch/common-1.c) is '#include
"common-1.h"' and if there is a common-1.h.gch but no common-1.h, the program
will say it can't find common-1.h.
./common-1.c:1:22: fatal error: common-1.h: No such file or directory
#include "common-1.h"
^
compilation terminated.
