Yes and no.

Making long 32 bits while most other 64-bit platforms make it 64
bits limits the portability of code that assumes that long is 64
bits, or that pointers are the same size as long.

Making long 64 bits would limit the portability of code that assumes
that long is 32 bits -- and apparently there's a lot of code like
that on Windows.

Either choice is perfectly valid, and does not hurt the portability
of well-written code that doesn't assume a particular size for
type long.  Microsoft had a choice between possibly breaking code
written for other platforms, and possibly breaking code written
for earlier versions of Windows.  I find it difficult to argue that
they made the wrong choice.
