Subject: Autoconf: Avoid incorrectly include the libpcap's config.h
X-Git-Url: https://git.tcpdump.org/tcpdump/commitdiff_plain/ccee9549f927eb13f869ee0db10c53c445191b8f

Autoconf: Avoid incorrectly include the libpcap's config.h

Fix the problem when configure like following is done:
./configure CFLAGS='-I../libpcap -I.'
This gives:
CCOPT =  -I../libpcap -I. -W -Wall [...]

See also the GitHub bug report #1313.

In Makefile.in, there is:
INCLS = -I. @V_INCLS@

Put $(INCLS) first in FULL_CFLAGS.
