The stdint.h and inttypes.h headers as required by the C standard are nowhere to be found, in ape or elsewhere. This makes compiling modern Unix software harder than it needs to be. The attached files, based on BSD headers, should be suitable on most architectures.

how very un-plan9-ish... these object oriented concepts were discarded by design, try finding a way to use files, everything is a file. maybe build a wrapper which creates the files based on types defined by stdint so that it functions similarly...
