This appears to be done by both Cygwin and the MSys version of bash. 
Windows itself preserves the case of environment variables (although
lookups are case-insensitive).

I have no idea how to resolve this, other than changing both g.parser
and all of the scripts which use it.

It might be worth checking whether the Korn shell from Microsoft's
Services for Unix exhibits the same behaviour.
