[Rd] R, AIX 64-bit builds - trying to understand root cause for message: "Error: Line starting 'Package: tools ...' is malformed!"

Ok, found the problem - on platforms that support it TRE uses wint_t (from wchar.h) as its type for characters (tre_cint_t) which on AIX is *signed* int. TRE uses liberally conversions between int and tre_cint_t apparently assuming that the latter is unsigned so conversions back to int are suitable for comparisons etc. On other platforms wint_t is unsigned so it works. Manually defining tre_cint_t to unsigned int fixes the issue.
Cheers,
Simon
