[Bug preprocessor/29276] New: C preprocessor run on Objective C code

["roberthensing at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Everytime I try to compile the libFoundation sources the preprocessor complains
with error messages like these:

NSObject.m:382:1: error: pasting "(" and "[" does not give a valid
preprocessing token
NSObject.m:513:1: error: pasting "(" and "[" does not give a valid
preprocessing token

I had to preprocess the source with the -x objective-c flags, forcing cpp to
process the file in Objective C mode and it worked fine.

I would have attached the preprocessed file, if there would have been an option
to make the preprocessor only include files and not expand macros but I
couldn't find it in your documentation. I might have overlooked it.

Sources can be found here:

GCC was invoked like this:
gcc -fPIC -fgnu-runtime -I.. -g -O2 -fobjc-exceptions -Wall -DDEBUG -c
NSObject.m -o shared_obj/NSObject.o

Adding the -x objective-c flags to the gcc command line did not work.
