Like me, for instance? I came onboard in '98 and talked to most of the
initial developers who had eventually stampeded away from the (to them)
distasteful duty of working on Windows. I'd been involved with cygwin
(aka gnu-win32) since early '97.

Posix paths were one of the main reasons for cygwin. The goal was to to
modify tools like gcc and make as little as possible so that Cygnus
could have a Windows toolchain but not force tool developers to deal
with modifying every line of code which assumed that '/foo' meant "the
file foo in the root directory" rather than "the file foo at the root
directory of the current drive" or "the foo option".
I've been managing support for cygwin and have had to answer the "Why
doesn't gcc deal with my c:\include paths very well" questions for
years now. Most people get the concept once it is explained to them.
YMMV.
So, anyway, fork, exec, and posix paths were the main motivations for
cygwin. Once I came onboard, you could add signals to that list, too.
But, hey, if you don't believe me, then maybe Larry Hall has more
credibility. He's been around longer than I.
