Subject: Add OSTYPE build-system variable, and use it
X-Git-Url: http://git.megacz.com/?a=commitdiff_plain;h=5775d5142da227d65fb86994d363eb16841ee642;hp=5775d5142da227d65fb86994d363eb16841ee642;p=ghc-hetmet.git

Add OSTYPE build-system variable, and use it

The use is in install.mk.in, where we need to know when
we're on Cygwin.

This fixes the build on my Windows box, where I have
both Msys and Cygwin.
