Erk! I'm not familiar with NTFS but the thought of this scares me, I 
expect you'd be opening yourself up to a world of hurt as:

a) NTFS isn't a first class citizen of Linux.
b) according to wikipedia NTFS has a 255 character filename limit - I 
don't know for certain this is a problem but I wouldn't be surprised if 
it is.

Will you be storing anything on the disk that isn't build related? If 
you anticipate doing a lot of builds you really want to a) use a 
filesystem that is Linux native and b) tweak the filesystem to reduce 
the number of writes made.

If you just want/need to be able to look at the build system pieces 
under WinOS then you could try:
