Bug #: 50048 Summary: "cc1: note: obsolete option -I- used, please use -iquote instead" during bootstrap Classification: Unclassified Product: gcc Version: 4.6.1 Status: UNCONFIRMED Severity: minor Priority: P3 Component: ada AssignedTo: unassig...@gcc.gnu.org ReportedBy: ludo...@ludovic-brenta.org Host: i386-linux-gnu Target: i386-linux-gnu Build: i386-linux-gnu During bootstrapping with ada enabled, I get this message multiple times: cc1: note: obsolete option -I- used, please use -iquote instead because of line 250 in gcc/ada/gcc-interface/Makefile.in. Recent changes in the glibc header files have caused GCC to fail to bootstrap on i386; see http://bugs.debian.org/637418. Replacing -I- with -iquote as suggested fixes this.
