The problem that Ulf is referring to is one of licensing, as described at
http://lists.gnu.org/archive/html/bug-gnu-utils/2004-01/msg00058.html
MSVC7 links with version 7 of the C runtime library by default, which
doesn't ship with Windows. As a result, GPL software built with MSVC7's
default settings can't be publically distributed.
It might be possible to force MSVC7 to link against the older MSVCRT.DLL
(which does ship with Windows), or possibly even link against the Cygwin
DLL.
