bug#6792: 24.0.50; at revision 100946 GNU Emacs with Xaw3d does not compile

[Peter Dyballa]

Hello!

In Mac OS X (here: 10.5.8, Leopard) Xaw3d is not standard. It can be  
installed by the package management systems Fink or MacPorts, then in / 
sw/{include,lib} or /opt/local/{include,lib}. When I change the  
configure script to use GCC_TEST_OPTIONS="-I/sw/include -L/sw/ 
lib" (line #3270) it finds the software, but does not propagate these  
*test* options to active flags. So this error happens:

gcc-4.2 -c    -I/usr/X11/include -I/usr/X11/include -I/usr/X11/include/ 
freetype2   -Wold-style-definition -Wdeclaration-after-statement -Wno-

and similarly with lwlib-Xaw.c. When I use MacPorts' Xaw3d the C  
header files are found because the non-Apple X11 installation has PC  
files which set CFLAGS to contain -I/opt/local/include.

Xaw3d does not come with a PC file so configure cannot rely on pkg- 
config.
