gcc 2.95.2 can't find X11 includes

[Doug Wyatt <dwyatt at kohlmansystems dot com>]

Hi,

I'm trying to build GhostScript on HP-UX with gcc 2.95.2 and
I've run into a compile problem that looks like gcc isn't
actually searching the include directories.  Probably I'm
just being dense (I haven't done much source compiling in
the last few years), but perhaps some kind soul could point
out something I'm missing.

The following is an excerpt from the make output:

gcc -v `cat ./obj/cc.tr`  -O2 -Wall -Wstrict-prototypes
-Wmissing-declarations     -Wmissing-prototypes -Wtraditional -fno-builtin
-fno-common -I./obj -I./src
    -I/usr/include/X11R6 -o ./obj/gdevx.o -c ./src/gdevx.c

I've verified that these include files exist both in /usr/include/X11R6
and in /usr/include and the two copies are identical.  The files are
referenced as, for example,

#  include <X11/Xlib.h>

I don't know if it makes any difference, but gcc was built on an HP9000
700 series and I'm running this compile on an HP 800 series server.

Can anyone give me a clue?  I'm not subscribed to the list, so please
cc: me in any replies, though I will monitor the archive.

Thanks,
