Doesn't Tcl have the equivalent of sizeof(void*) or sizeof(size_t)?

Ah, interesting, thanks (I missed this one before).
Is there a theoretical difference between the wordSize and pointerSize
(disregarding the fact that it's AFAIK language-dependent what size a long is)?
"wordSize" is sizeof(long) [1] and is compiler dependent (and of course
influenced by the data model ILP32 vs. LP64). The C standard just
defines that sizeof(long) must be greater or equal 32 bits.
"pointerSize" refers to sizeof(void*) (in c99 lingo " generic object
pointer").
