Description Rafał Mużyło 2008-03-24 20:25:31 UTC 
I'm building gcc with following useflags:
doc fortran gtk libffi mudflap multislot nls objc objc-gc openmp (-altivec) -bootstrap -build -gcj (-hardened) -ip28 -ip32r10k (-multilib) (-n32) (-n64) -nocxx -objc++ -test -vanilla
I learned that --libstdcxx-pch can be passed to libstdc++ configure to disable use of precompiled headers while building. As toolchain.eclass is very confusing, I wonder if a pch useflag can be added to the ebuild ?

That's --disable-libstdcxx-pch, of course.
