  Merge branch 'msvc' into master
  
  Commits merged from msvc:
   - warnings: fix buglets for portability warnings
   - tests: extend tests on 'extra-portability' warning category
  
  Extra testsuite edits:
  * tests/extra-portability3.test: Use `$original_AUTOMAKE' instead
  of hackishly extracting the first component of `$AUTOMAKE'.
  * tests/extra-portability.test: Likewise.  Also, since we are at
  it, throw in a couple of small extensions and tweakings (suggested
  by the minor merge conflicts).
