Re: Mingw32 Futures


EGCS works fine without cygwin.dll, I simply can't do much without
all the unixy extras I've come to depend on, so I just keep cygwin
around for the utils like bash, but we're working on porting more.
I'd say EGCS and GCC2.8.0 are ~equivalent. (my opinion) EGCS is just
maybe more bleading edge, but I like it. EGCS derived from Jan-Jaap's
original work BTW.
