[Debian GNUstep maintainers] Bug#457555: gnustep-examples: FTBFS on powerpc: /tmp/ccNxCrcq.s:657: Error: symbol `.LCF0' is already defined

[Yavor Doganov]

Package: gnustep-examples
Version: 1:1.2.0-1
Severity: serious
Tags: patch

The package fails to build on powerpc:

I can't reproduce this with -O1 and -O2, so I propose the attached
patch as a workaround.  According to Policy binaries have to be
optimized anyway.  Apparently there is a bug in gnustep-make as well,
because as per the GNUstep Make manual `-O2' is set by default (which
doesn't happen here).

It could be possible that this arch-specific bug is in GCC.  FYI I can
still reproduce the error with `-O0' and gcc-snapshot on my scruffy G3.
