Re: POSIX subsystem for Windows NT...
SFU became SUA because they didn't like the acronym maybe?
the command line utilities were missing things like 'tar' (but it had 'pax' instead, go fig)
It had libs for X11R5 <-- yes, 5
it had an ANCIENT version of gcc on it
it didn't work very well with autotools
I couldn't compile certain gnu libraries, even after trying really really hard
there were numerous header incompatibilities and missing features
in short, it was already ~10 years out of date when I finally realized it existed, and installed on XP, then later on 7, to discover that it was being discontinued and would NOT install on any later version of winders.
ABANDONWARE, to say the least.
How about Cygwin, instead?
