Every vcbuild and msbuild invocation ought to recognize this variable, so
please update the two places involving ecpg_regression.proj. Apart from that,
the patch looks good.

I was tempted to back-patch this. The risk to back branch users seems
negligible, and it would be convenient for me as a person who builds all
branches. That reason is not good enough, so I plan not to back-patch. I
feel like I might be missing a stronger reason to back-patch.
