As to making NO_REGEX conditional on REG_STARTEND: you are talking about
apples and oranges here. NO_REGEX is a Makefile flag, while REG_STARTEND
is a C preprocessor macro.

Unless you can convince the rest of the Git developers (you would not
convince me) to simulate autoconf by compiling an executable every time
`make` is run, to determine whether REG_STARTEND is defined, this is a
no-go.

But just to clarify, does anyone have any objection to making our
configure.ac compile a C program to check for this sort of thing?
Because that seems like the easiest solution to this class of problem.
