I believe there are case sensitivity changes in gdb already.
Ah, yes, here we  are.

set case-sensitive off

Right now, pascal is defaulting to case_sensitive_on, instead of
case_sensitive_off.

Just edit p-lang.c, search for case_sensitive_on, and change it to
case_sensitive_off,, and you should be in business.

Sure. Do it the right way, of course, and don't make it a bunch of
hacks.
