I bit of guesswork, since I never bootstrapped MinGW myself, but:

MinGW/native Windows apps don't know a thing about the /home/bobbybrasko
cygwin mount and xgcc should be a MinGW app.
That's why Danny has the following cygwin mount, and he puts the 
sources/builddir there:

c:\developex on /developex type system (binmode)

This way, both cygwin and MinGW will resolve the /developex path to the 
same dir.
(/ on the MinGW side will resolve to the root of the current drive.  )
