Re: CreateProcess() - executed program gets different argument depending if it's compiled with gcc (cygwin) or cl (VS)?

'\' is an escape character in C, Unix, and Linux.  In Windows, it's a
path separator.  Use '/' instead when working with Cygwin and you'll
avoid allot of problems.  Better yet, use POSIX paths exclusively.

"\\hostname" is remote path location, I don't think I can use "//hostname" instead, either for cygwin program and especially not for not-cygwin program, can I? (can't check it now)

With Windows, you're free to use either path separator. With Cygwin, you're life will be easier if you use '/' though it will accept '\' too if properly escaped.

Cygwin understands UNC path syntax using '/'.  I would expect
Windows to be cranky about '//' as a UNC path indicator though.
If you need the source to compile, link, and run appropriately
on either compiler, then you need to port it so it will, if that's
what you're concerned about.
