 Module Name:	pkgsrc
 Committed By:	maya

 Modified Files:
 	pkgsrc/lang/gcc49: Makefile

 Log Message:
 gcc49: don't use precompiled headers for libstdc++

 this is a build time optimization that causes hangs on some machines
 (netbsd-7/i386, but not netbsd-7/amd64). disable it globally instead
 of guessing which are broken.

 gcc{5,6} are already disabling it.
