One goal of Mingw is source level compatibility with MS compilers, and I
for one see no reason to move away from that.

I agree on this issue. I've made the change, but need to test it first
before I unleash it. I was hoping to have a new runtime snapshot this week,
but looks like it'll have to wait till the weekend.
The runtime snapshots are in
The current changes in my tree include (not exhaustive list):
- lots of header additions -- wide character api prototypes, incomplete
but a start; tchar.h additions; fixes to various DLL imported variables;
- quite a few w32api changes. Anders Norlander already has some of these
changes, but there are a quite a few that I'm still working on. One
remaining issue is merging in the changes that have been made to Cygwin
development snapshot version, and that's what I need to do now.
- Thread-safe C++ exception handling. This allows the use of pthreads
(POSIX Threads) package. This is still experimental, and subject to
change. You'll need my next release of gcc to take advantage of it
- change in DLL startup code to avoid linking in CRTDLL/MSVCRT. Untested
as of yet.
