configure tries to compile a variety of throw-away programs to check
for the capabilities of the system.
Lots of errors in config.log are expected.
You should only look at config.log if configure reports an error and
fails to generate the Makefile.

Here it probably tries to find the switch that prints the compiler version.
It has to try every known switch that does that; but no  compiler will
accept every possibility.
These errors are harmless. They tell configure that GCC doesn't
support the -qversion switch
(-qversion is accepted by IBM's XL C/C++ compiler for AIX).

Here it probably found out that OMP is not supported.

This suggests that OpenTimer thinks it's being compiled under Windows
(GetCurrentThreadId is a Win32 API function). It failed to identify
Cygwin as a POSIX platform. You could try submitting a bug report or,
if you're a programmer, fix it and supply a patch:

"OpenTimer is actively maintained by Tsung-Wei Huang. If you are
discovering any bugs or are interested in pursuing an OpenTimer-based
project with me, please contact"
