            Bug ID: 107607
           Summary: tools-src/calcpath uses unportable realpath(1)
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: modula2
          Assignee: gaius at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---

When trying to build the devel/modula-2 branch on Mac OS X 10.7/Darwin 11, =
it
failed when executing gcc/m2/tools-src/calcpath since that Darwin version
doesn't
have realpath(1) at all.  It isn't mentioned in the Autoconf docs which are=
 a
good source for portability advice.  The possible alternative readlink -f
cannot be used either because, while the command exists, the native version
doesn't support the -f option.

I'm currently cheating by using the coreutils 9.1 version, but building that
on Darwin 11 is sort of a nightmare and seems way overkill just to run a si=
ngle
script.=
