Subject: tap: Include <config.h> as needed.
X-Git-Url: https://git.draconx.ca/gitweb/dxcommon.git/commitdiff_plain/a686e811e9fb465ed7c8d88f75915489fc7d09f0

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.
