Use gcc for C or g++ for C++.

Which shell?

bash-2.05b$ man -w
/usr/X11R6/man:/usr/man

These are also listed in /etc/man.config, which also lists some other
paths, but they don't exist in the file system so I think man just ignores
those.

bash-2.05b$ ls -l /usr/man/man1/ls.*

It's not a UNIX emulator; you can't run UNIX binaries with it.  It just
emulates some common UNIX APIs at the source code level so you can port
UNIX apps to Windows for those people who can't run UNIX for whatever
reason.

You can also use the -mno-cygwin option with gcc/g++ to compile your
program as a standard Win32 program that uses msvcrt.dll (instead of a
Cygwin program that requires cygwin1.dll), but doing this restricts the
number of libraries you may use, eg. from memory you can't use -mno-cygwin
and -lncurses.
