Re: pthreads-win32 2.8.0, stack alignment, and SSE code

I've just read this whole thread for the first time. I haven't come 
across this issue of alignment on Intel processors before so I thought 
I'd better at least Google around the subject before replying. 
Unfortunately I've got to run now and won't be reading mail for another 
5 days or so.

I would very likely include the patch as a build option, so I'm 
wondering if you've tried building the library with the -mstackrealign 
gcc flag that does the same thing as force_align_arg_pointer (I haven't 
tried either of these but read about it).
