[gtk-gnutella-devel] Massive warnings "ISO C forbids braced-groups within expressions"

[Lloyd B. <llo...@ms...>]

Just upgraded to Ubuntu Jaunty (9.04), and when recompiling GtkG (svn 16499), I am seeing tons of the warning message "ISO C forbids braced-groups within expressions".  Here's a sampling:

It seems that every assert throughout GtkG is triggering this warning (and there are a LOT of them :)).

I suspect this is a result of picking up a new gcc version with the upgrade.  Here's the version I'm using:

lloyd@dell:/usr/local/src/gtk-gnutella$ gcc -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.3.3-5ubuntu4' --with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.3 --program-suffix=-4.3 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --enable-targets=all --with-tune=generic --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu
Thread model: posix
gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4) 

Any clues?
