Emacs 21.0.104 Ignoring --includedir

[Vin Shelton]

Last night I built the Emacs-21 104 prerelease on my linux machine at
home using a prefix of /usr/local.  This worked fine.  Today here at
work I attempted to build the Emacs-21 104 prerelease with a more
unusual prefix and my xpm and png include files were not found.
Here's what happened:

First I attempted to configure in my usual way:

../../../src/emacs-21.0.104/configure  --prefix=/u/shelton/new/SunOS-5.5 
--datadir=/u/shelton/new/share --disable-nls

this caused neither xpm nor png header files to be found.  So I
explicitly specified both '--includedir' and '--with-xpm' and this did
not work, either.  Here is the part of config.log relevant to xpm (I
ctrl-c'ed the build at this point):

configure:5103: checking for X11/xpm.h
configure:5113: gcc -E -I/usr/openwin/include      conftest.c >/dev/null 
2>conftest.out
configure:5109: X11/xpm.h: No such file or directory
configure: failed program was:
#line 5108 "configure"
#include "confdefs.h"
#include <X11/xpm.h>


It appears to me that, although I specified '--includedir' on the
command line, that option did not get passed on to gcc.

HTH,
