wow thanks...learned something new.

I'm sorry when I was in university there were still SPARC64 machines around, which use the "ILP64" where the default int size increased to 64 bits, so that must have been why I was taught that the default int size increased when going to 64-bit arch.

Sun-shipped 64-bit Solaris has 32 bit int and it's in the LP64 column of the Wikipedia table. The entry of a ILP64 HAL systems version is about this other niche Solaris port for HAL designed chips that was not commonly used in universities (or anywhere, for that matter).

oh gosh, my Sun Solaris system must have been on 32-bit ints in that case.
