`checking size of mp_limb_t... 0` and `configure: error: Oops, mp_limb_t doesn't seem to work` when compiling the Microchip XC32 compiler from source

[Gabriel Staples, ElectricRCAircraftGuy.com]

"Stinking" and "stinker" are playful terms in American English--things
you'd call your little kids when they're being cute or funny. It's more of
a playful term. In this context it expresses excitement that I found the
bug. To a non-native American English speaker, I can see the confusion. I
was very calm when I wrote it.

I can see the confusion. I took the word out.

> Can you explain concisely in which way absolute include paths made gmp
configure break in your environment?

In the answer <https://stackoverflow.com/a/77435216/4561887>, please jump
halfway down, to the section titled "Explanation of the
${gcc_srcdir_RELATIVE}/configure relative path fix that works". I can
neither explain it more nor less simply than that.

At this point I'm no longer seeking help, but rather just sharing my
findings in case it helps someone else.

Sincerely,

Gabriel Staples
