If one configures with --disable-boostrap --enable-languages=c and then builds with make bootstrap but doesn't have ada installed, the build fails. The problem is that gcc/configure unconditionally adds ada to the stage 1 languages BOOT_LANGUAGES, even though --enable-languages=c is used.
In non--disable-boostrap builds I think this was fixed by the patch in: http://gcc.gnu.org/PR24252 (that was incorrectly attached to the wrong PR, but the patch is the one that seems to cause it to work). This is a regression -- Summary: REG: --disable-bootstrap && make bootstrap doesn't work Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: mrs at apple dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29531
