guile-1.8.1 build fails at libguile/posix.c on Solaris2.6

[anirkko]

Hi
The guile-1.8.1 build also fails at libguile/stime.c on Solaris2.6
(see output below; configured with --without-threads which was necessary
because the default --with-threads also didn't work, see previous reports).

Reason:  variable len is not declared, because the declaration
is in a "#ifdef __MINGW32__" and the condition that determines
whether the variable is used or not is a "#ifdef HAVE_UNSETENV" / "#else"
Thus, if both Macros are undefined, the error results.

Workaround:

replace the #else
with
  #endif
  #ifdef __MINGW32__

Then it builds, but maybe it should be checked if it does what it should...?

I believe this has been fixed in CVS:

  http://cvs.savannah.gnu.org/viewvc/guile/guile-core/libguile/posix.c?view=log&root=guile&pathrev=branch_release-1-8

Thanks,
Ludovic.
