Try putenv(), that's available under mingw.

I've a crude hack which allows a command line flag -l (or --lang) to
be followed by a LANG environment variable:

gnubg --lang de_DE.ISO8859-15
gnubg --lang it_IT.ISO8859-15
gnubg --lang en_US.ISO8859-1

Will take a currently UK English version and display it in
German/Italian/US English (mostly checker)

This should work under Windows as well.
It would be nice if this could be parsed out of the command file, but
the command file handling doesn't begin until after gtk has been
started. 

Note that the weird processing of some arguments before setting up gtk
and some after means this does not work for text mode.

It's not clear to me why we process some command line arguments, then
set up the GUI (if required), then process the rest of the command
line. I suspect this is historical and that all the arguments could be
processed before GTK and the GUI start up, in which case my fix would
also work for text mode.
