Emacs with GNUstep

["Germán A. Arias" <german@xelalug.org>]

With pretest 24.2.91 I had a problem to compile. I get something like:

gcc -std=gnu99 -rdynamic -Demacs  -I.

the gnustep libraries flags are present. But this don't works. Googling
I found this:

http://stackoverflow.com/questions/11425120/objective-c-on-linux-compile-error

So, I solved the problem adding "-Wl,--no-as-needed" at line 4360 in configure.ac:

LD_SWITCH_SYSTEM_TEMACS="${LD_SWITCH_SYSTEM_TEMACS} -L
${GNUSTEP_SYSTEM_LIBRARIES} ${GNUSTEP_LOCAL_LIBRARIES}
-Wl,--no-as-needed -lgnustep-gui -lgnustep-base -lobjc -lpthread"

Could be possible add this flag in trunk? Thanks.
