First of all we should define (make a list) which systems/compilers we want to 
support. With this list we can definitely decide about C89 vs. C99.

AFAIR, C89 is still the standard that GNU projects should aim at. But we could 
simply ask the gnulib people where the train goes.

@Darshit I recently experience some warnings from gnulib code, but not that 
many... could you give us more details about your setup ?

Basically I get warnings because of -pedantic.
