Comment (by thomie):

 Can't we just make life easy for the majority of developers, and require
 GNU tools.
 There are already so many things to keep in mind when submitting a patch
 to GHC, why make it even harder?

 What's the problem with installing GNU tools on Solaris?

 It would also free up time to fix *actual* problems on Solaris (there are
 plenty, judging by the failing tests on the nightly builders), not these
 silly compatibility issues.

 For reference, in `configure.ac`:
 {{{
 dnl ** Find the path to sed
 AC_PATH_PROGS(SedCmd,gsed sed,sed)

 dnl ** check for time command
 AC_PATH_PROG(TimeCmd,time)

 dnl ** check for tar
 dnl   if GNU tar is named gtar, look for it first.
 AC_PATH_PROGS(TarCmd,gnutar gtar tar,tar)

 dnl ** check for patch
 dnl if GNU patch is named gpatch, look for it first
 AC_PATH_PROGS(PatchCmd,gpatch patch, patch)
 }}}

     Look for sed as gsed first
     Solaris's sed apparently doesn't understand [:space:]
