Subject: [PATCH] tap: Include <config.h> as needed.

When using a config header in Autoconf, it is necessary to #include
that header before including anything else that might be influenced
by configure tests, which includes standard C headers.

In particular, things can go completely off the rails if Gnulib is
involved and generates replacements for the standard headers used
by this file.
