[pcre-dev] using 'diff -u' in 'make test'

hi all,

when running 'make test' your framework ends up invoking 'diff -u'.

if it's not strictly necessary to get diffs in unified format, you should
consider getting rid of the '-u' flag. it is not supported on some platforms,
in particular:
HPUX 11
AIX 5.2
SOLARIS 5.8

... and probably others but those are the only ones i've explicitly tried.


i'm done harrassing y'all now. i've got pcre-7.6 compiled on the 17 different
platforms i need to support. thanks!


cheers,
-zach
