I would think this is not a big problem if the Windows user is supposed to
install gcl on his machine with an installation program ? The lib can be
in the same directory of the exe that uses it, or the installation program
can install the lib in the Windows directory (to avoid multiple copies on
the hard disk) ?

If this can help : there exists a zcat.exe from the package UnxUtils by
Karl Syring,

http://www.weihenstephan.de/~syring/win32/UnxUtils.html

that does not require Cygwin, cf. Karl's comments:
"Here are some ports of common GNU utilities to native Win32. In this
context, native means the executables do only depend on the Microsoft C-
runtime (msvcrt.dll) and not an emulation layer like that provided by
Cygwin tools."

I would say that both seem possible and reasonable?

Best wishes,
