Rebased to follow changes on your branch.

@jacobly0 from this file https://github.com/c4ooo/TI84-CE-Wrapper-for-Monochrome-TI-BASIC-Programs./blob/master/ti84pce.inc I can figure out where those builtin function names originate from. Can I assume that you have some access to the sources for those functions?...

Wow, that's a great response, thanks a million :)

I observed something odd today while trying to use stdint.h's uint32_t type, sizeof(uint32_t) is... 2 (while it's 4 with sdcc as everywhere else...) fortunately, sizeof(unsigned long) is 4.

You were right, clang's stdint.h was including-next host's stdint.h unless -U__STDC_HOSTED__ flag is passed, this solves big ints sizes problem, thx!

Hi @jacobly0, can I ask for your implementation of `__lcmpu`?
