[svn-r8938] 
Purpose:
Bug fix

Description:
Modification time test (mtime) would die silently on some systems.  This is
because the code is very system-dependant (it relies on getting the current
time and the timezone from the OS).

Solution:
mtime test now uses TEST_ERROR macro to print "FAILED" and to output where the
failure occurred.  Configure script is a little smarter about whether
gettimeofday() function returns the timezone correctly.
Further bugs will need to be addressed on a system-by-system basis.

Platforms tested:
sleipnir, arabica, verbena, copper, windows (VC7)
