Uhm - sure that mod_status and a few others didn't also need this
on some platforms due to double/float arithmetic (statistics?)

Cool, leaving the change on trunk, we can enhance it later after we
determine an appropriate AP_NEEDS_LIBM macro test for the particulars.
This is what alpha's are for :)

That's the platform I do most tests on. I compiled all trunk modules and
could load them, so no missing symbols.
I do the same change regularly for 2.2.x, so I know it works there to
(but didn't test there with all more exotic modules).

Correct, but if I remember right, manipulating long long's into doubles
on solaris 8 and several other operating systems involves libm stub helpers.

It's always hard to be sure for all platforms, but at least it works on
Solaris and Linux, and I can't find any libm symbols in mod_status.
The floats there are only used in simple divisions and printf.
As I understand it, Windows builds are not influenced by these changes,
because they use a separate build apparatus?
