Subject: Fix a few compiler errors reported correctly my MSVC 9.0. Fix
 libtests test suites to pass on Windows, mostly by dealing with ascii vs.
 binary and NL vs. CRNL change ($td->NORMALIZE_NEWLINES). Convert some test
 suites to use fread instead of read. PCRE.hh: define PCRE_STATIC if on
 Windows. Provide cross-platform function for getting current time instead of
 using time(0).
