Here and other places you indent braces incorrectly.  Please fix.

Better to divide by sizeof (regnames_64[0]), then it's obvious in
just this one line of code that you're calculating an array size.

Same thing here.

while (ISALNUM (*p))

Why not save it when it is 0 too?  Saves a test, here and later when
you restore.
