A UnixWare related bug

[Stepan Kasal]

Hello,
  Roger Cornelius has reported the following bug on address@hidden;
I'm forwarding it to bug-libtool list.

I have verified that the same bug is still present in CVS HEAD.

As you surely notice, the patch cannot be applied as is: it would move
the pattern "sysv4*uw2*" before the more specific "sysv4.2uw2*".
But I'm sure the correction is obvious (for you, not for me ;-).

Thank you again Roger, for reporting the problem and analysing it,
        Stepan Kasal

Subject: autoconf 2.59 bug

There is a problem in the configure script generated by autoconf v2.59
for at least some packages.  I've seen it in the autoconf v2.59
generated configure script for ImageMagick 6.0.4, and the library
packages, libtiff-3.7.2 and liblcms-1.14.

The problem is with matching sysv5UnixWare7.1.4 in $host_os.  The case
for sysv5* is matched before the case for sysv5UnixWare7*.  This is also
true for sysv5OpenUNIX8* and sysv5uw[78]* values of $host_os. 

For libtiff and liblcms, this misidentification results in the
$lt_cv_deplibs_check_method var being left in the default state of
"unknown" rather than being set to "pass_all", and ultimately prevents
the shared libraries from being built.

Attached is a patch with enough context to exemplify the problem.  This
is from the configure provided with liblcms.
