I'm trying to build an F# project with XNA support on

vs2008. The XNA DLLs are not installed into the GAC and instead are

installed in the program files directory, and I had to include the search path

using the -I flag. Problem is that I'm working on this project from

multiple machines, one being 32bit and the other being 64bit so the program

files path is different on each.

I tried using the environment variable "%XNAGSv3%" to specify the

location of the DLLs but F# projects don't do environment variable expansion

when executing the compiler. Fine, no big deal, I said to myself and

wrote a batch script to handle the include paths and set it as the custom

compiler value in the project options. Now my problem is that the custom

compiler value can't handle relative paths, environment variables or macros and

if my SVN checkout path is different on each system I'm screwed.

Oh FYI: There is a minor UI bug; the "..." path

select button for the custom compiler option is active only when the custom compiler

option is deselected.
