Improved msvc support.
- minor spellings errors in comments ("iff" and "vccars" instead of "if"
and "vcvars")
- correct escaping of metacharacters in regular expressions
- Fixed a condition so /Zc:forScope /Zc:wchar_t are added in MSVC 8.x too
- Side-by-side manifests are now used for exe targets too, not only for
DLLs.
- Reworked /Ogity|/Ogisy options selection code (a minor refactoring)
- Search paths without /bin are now only added if vc 7.1 is going to be
detected.
- Added autodetection for VC8.0 using VS80COMNTOOLS variable
- Use os.environ instead of modules.peek + :J hack.
Patch from Andrey Melnikov.
