Thanks for raising this on the list, I just posted these comments to the 
Trac ticket:

"IMO this is the wrong fix: our code should make no assumptions about the 
actual type of uintXX_t etc.

IMO the preprocessed headers are just plain wrong - you can't mix concrete 
types (char short etc) with typedefs (intXX_t) because you're just asking 
for problems with duplicate specializations. It has to be all real types 
throughout.

BTW in addition to the two platforms mentioned above, this is also broken 
for Sun on Linux.

Reassigning to the person who made these changes..."

Not sure if we can fix this for 1.49, but you're right, it is a high 
priority.

Hopefully Brandon Kohn is reading this as he made those changes?

John.
