Re: [MinGW-dvlpr] SSE2 and msvcr71.dll

[Luke D. <cod...@ho...>]

Based on this discussion:

http://article.gmane.org/gmane.comp.gnu.mingw.user/8916/match=msvcr71

I think it would be a good idea to add a compiler switch to select the
runtime library. If the "-mcrtlib=<name>" switch is not feasible to do in
specs then "-mmsvcr71" should be good enough. For the headers, do you intend
to just add the new functions unconditionally so that a link error occurs if
you use __aligned_malloc() but don't use -lmsvcr71? (Sounds okay to me but
it's worth mentioning)
