(Aain, those warning are turned into errors by -Werror).autoconf's test programs tend to be sufficiently sloppy that I would expect -Werror to break a whole lot of things, not just this. We can possibly neaten up the particular test case but there are many tests whose expansion we don't have much control over.
Yeah, I expected all hell to break loose - only to be pleasantly surprised by this being the only issue I encountered. So I figured fixing this might be worthwhile - even if this surely does not fix -Werror builds on all platforms and/or compilers. Alternatively - is there a way to use -Werror only for building the actual sources, not the configure tests? I didn't find one, but my autoconf-fu is pretty limited... best regards, Florian Pflug
