[Buildroot] Compile error: makedevs.c - warnings treated as errors

[Joe George]

I am getting a compile error due to warnings.  I probably have
something setup wrong but I haven't been able to figure out what.  The
makedevs.c file has not changed from an earlier buildroot snapshot
that compiled.

cc1: warnings being treated as errors
/media/swdev/buildroot/build_powerpc/makedevs/makedevs.c: In function 'main':
/media/swdev/buildroot/build_powerpc/makedevs/makedevs.c:531: error:
ignoring return value of 'system', declared with attribute
warn_unused_result
make: *** [/media/swdev/buildroot/build_powerpc/makedevs/makedevs] Error 1

Any ideas?

Thanks,
Joe

I've just replaced that line in makedevs.c with

   int r = system(...);
   if (r) {}

Temporary gross workaround and all, but it let the compile continue.

Fixed in r24236, thanks to a patch provided by Jeremy Kerr.
