When emerging sys-devel/gdb-7.2 the process stops at the configure step with the following error message: [snip] checking whether strsignal is declared without a macro... yes checking whether strverscmp is declared without a macro... yes checking whether <wchar.h> uses 'inline' correctly... no configure: error: <wchar.h> cannot be used with this compiler (i686-pc-linux-gnu-gcc -O2 -march=native -pipe -fomit-frame-pointer ). This is a known interoperability problem of glibc <= 2.5 with gcc >= 4.3 in C99 mode. You have four options: - Add the flag -fgnu89-inline to CC and reconfigure, or - Fix your include files, using parts of <http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=b037a293a48718af30d706c2e18c929d0e69a621>, or - Use a gcc version older than 4.3, or - Don't use the flags -std=c99 or -std=gnu99.

Please, paste your "emerge -pv gdb" output.
Also, give it a try without ccache. I don't know the behaviour of ccache in configure phase, but it won't harm to try without it. gdb-7.2 was marked stable in x86 some days ago, which means that your error didn't hit our x86 arch testers.
Also, attach your full build and config logs.

Looks like deactivating ccache did the trick, gdb is compiling now. Many thanks!
