Whether gcc should issue the warning when math.h has not been included
is debatable. Whether apache should use names that match those in the
standard C library is also debatable.

I don't think so. Adding -fno-builtin-exp will disable gcc's builtin
exp and make the warning go away, but it would probably be better for
Apache to change httpd.h. The apache list would be the place to
discuss that.
