Many gnustep projects (including ones belonging to System domain)
use -Werror for compilation. Usualy they contain many makefiles and it requires 
removing this variable from all of them to make projects compile. I am using 
gcc 3.3 and I get warnings from each of those project, so i am not able to 
build them without digging into the project structure and removing all 
-Werrors. I have a suggestion: would it be possible to add some gnustep-make 
switch, like werror=yes to enable this warrning optionally, so developers do 
not have to include it in their makefiles and others can buld their projects 
despite of warnings?

Thanks Stefan - I'd suggest those project could do better - they could use
in their top-level GNUmakefile


the 'export' will cause it to be automatically passed down to all
subprojects, so they would set this only once in their top-level
GNUmakefile, and it's easy to turn it on/off.

Ok, that should work. However, why someone should modify ANY source files 
(including make files) just to be able to build the project which should be 
build without problems?

I have attached a patch that will add a switch 'check' that will enable -Werror 
flag. Other functionaklity behind this switch should be added later. To check 
your source files just type:

   make check=yes

and all warnings will turn into errors.
