Most UNIX tools play nicely on a VFAT/FAT32 mounted partition from Linux.
The important restrictions are that no links can be created and permissions
are ignored. I often CVS checkout/checkin directly from a VFAT partition
from Linux, and will occasionally autoconf/automake/build projects directly
from the VFAT partition without problems in most cases. Where I tend to run
into problems is building projects that are shared libraries, as libtool
(unless you explicitly tell it not to) gets configured for the build
environment which supports links (Linux), but tries to create hard links
from the (long-version).so to the (short-version).so files on part of the
build environment that doesn't (the VFAT fs).

I presume that the Windows file system is indeed a FAT file system (because
NTFS is very poorly supported under Linux), which has no concept of
Unix-style permissions. That probably makes Jam very, very unhappy.

I've found that FAT partitions under Linux are good only for communication
with Windows on the same computer, and are not in any way useful to
development. Between the lack of symlinks and the lack of permissions, Unix
tools just don't play nice.
