Thats probably this one:
[ "libraries/stamp/$p" -ot $tarball ]
It there's no other problem on Solaris, the whole `re-extract a
library if the tarball is newer' thing could be done with a single
shot of make(1), even using only those (very limited) features of
make(1) mandated by POSIX.

Giving up on those things that even more people will do unportable
stuff in the future.

And here we have that validation problem again. You can't expect
that everyone who sends patches has access to all those types of
operating systems. Nor can one expect all the GHC developers to
have access to other, more `exotic' systems.
