[webkit-dev] Win portability patches

[Krzysztof Kowalczyk]

I've submitted bugs 4627, 4629-4641, 4643-4646 for windows portability
of javascriptcore.

The patches do more or less what Justin's patches
(http://bugzilla.opendarwin.org/query.cgi?query_format=advanced&short_desc_type=allwordssubstr&short_desc=&product=WebKit&long_desc_type=substring&long_desc=&bug_file_loc_type=allwordssubstr&bug_file_loc=&bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED&emailassigned_to1=1&emailreporter1=1&emailtype1=substring&email1=justin%40xiondigital.net&emailassigned_to2=1&emailreporter2=1&emailcc2=1&emailtype2=substring&email2=&bugidtype=include&bug_id=&votes=&chfieldfrom=&chfieldto=Now&chfieldvalue=&field0-0-0=noop&type0-0-0=noop&value0-0-0=&known_name=Justin%20H%20bugs)
do but:
  - at the time I was working on my changes I didn't know about them
  - there hasn't been progress on those for the last month
  - I looked at the patches and comments and tried to incorporate that feedback
  - my version of GC does support multi-threading

I'll be happy to make any changes to those patches.

My goal is to make compiling on windows as easy as possible for
windows programmers. There's still some unavoidable additional work
(downloading icu and bison) but I tried to at least document this well
in win32-build.txt.

For those who want to experiment with the whole thing, I've all the
