"GNU compatibility environment" - what does this mean? I thought Cygwin
is a Unix/POSIX emulation. The system calls fork(), exec() and ioctl() are
older than GNU.

Since which version does it do this? The http://cygwin.com/faq/faq_4.html#SEC54
mentions that _some_ applications accept "c:/windows" instead of
"/cygdrive/c/windows". Do they also accept "c:\windows", and does this hold
for the entire Cygwin API?
