[Plplot-devel] Removing special Windows logic concerning qsastime_testlib

[Alan W. I. <ir...@be...>]

Hi Arjen:

To my knowledge, the work you did to get qsastime_testlib to build on
Windows never gave useful test results because of limitations in the Windows
C library time routines (e.g., no valid time results before 1970). I do
appreciate the work you put into this; it was the only way we could discover
those limitations in the Windows C library time routines. However, because
of those limitations, I have removed (revision 9930) all the special Windows
logic that you implemented in the build system and in the qsastime_testlib
code, and instead simply changed the build system logic to not allow an
attempt to build qsastime_testlib on Windows (i.e., when WIN32 is true).

With revision 9930, the qsastime_testlib.c code and the build system logic
are much cleaner for platforms (64-bit Linux and possibly 64-bit Mac OS X)
where qsastime_testlib actually produces useful results.

The new file lib/qsastime/README.qsastime_tests documents the applications
(currently qsastime_test, bhunt_search_test, and qsastime_testlib) used to
test the qsastime library.  Following directions in that file I checked that
I could still use the revision 9930 qsastime_testlib to reproduce
lib/qsastime/qsastime_testlib.out_standard on my 64-bit Linux platform.

I may not get to it this week, but I eventually plan to implement another
test which simply compares extensive libqsastime results with a file.  That
test should be useful on all platforms with no dependence on C library
time-handling routines and therefore no issues concerning peculiarities of
such time-handling routines on certain platforms.
