When bootstrapped with -Werror (should not everyone bootstrap with it ?), bootstrapping gcc fails with:
... In file included from /Users/regress/tbox/svn-gcc/gcc/attribs.c:37:0: /Users/regress/tbox/svn-gcc/gcc/plugin.h: In function 'invoke_plugin_callbacks': /Users/regress/tbox/svn-gcc/gcc/plugin.h:47:30: error: unused parameter 'event' [-Werror=unused-parameter] /Users/regress/tbox/svn-gcc/gcc/plugin.h:47:43: error: unused parameter 'gcc_data' [-Werror=unused-parameter] cc1: all warnings being treated as errors (see http://gcc.gnu.org/ml/gcc-regression/2010-04/txt00157.txt). The "Gcc [trunk revision 158897] failed to boostrap on x86_64!" is likely due to the same problem due to revision 158896. -- Summary: [4.6 Regression] Bootstrap failure: cc1: all warnings being treated as errors Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: dominiq at lps dot ens dot fr http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43935
