Re: gcc 2.95.2 can't find X11 includes

[Doug Wyatt <dwyatt at kohlmansystems dot com>]

I guess I wasn't too clear on this... to my understanding either
-I/usr/include or -I/usr/include/X11R6 should work because Xproto.h,
for example, is in these two locations:

-r--r--r-- 1 bin bin 56454 Sep 26 1996 /usr/include/X11/Xproto.h
-r--r--r-- 1 bin bin 56454 Sep 26 1996 /usr/include/X11R6/X11/Xproto.h

The first is actually a symlink to the second:
  lrwxr-xr-x 1 root sys 31 Jul 15  1997 /usr/include/X11/Xproto.h ->
     /usr/include/X11R6/X11/Xproto.h

The list shown after "#include <...> search starts here:" contains
/usr/include (a default), where <X11/Xproto.h> should have been
found.  This search list doesn't show /usr/include/X11R6, which it
should to my mind since I had -I/usr/include/X11R6 in XINCLUDES and
this value clearly made it onto the gcc command line generated by
the makefile.
