I'm not saying the library is wrong.

Of course the code _is_ bogus! The problem is, there is a lot of
such code out there.

If the PR is invalid, why there is "undef min" (and max) in the
stl_algobase.h, line 128?

Can there be any help for a sore programmer confronting the problem next
time? Just a hint to help to identify the place where the macro
redefines a reserved word?
