Revision 1.4, Sun Aug 10 23:54:41 2014 UTC (6 years, 3 months ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_13_3, VERSION_1_13_2, VERSION_1_12_4, VERSION_1_12
Changes since 1.3: +1 -3 lines

Get rid of HAVE_CONFIG_H, it is always defined; idea from libnbcompat.
Include <sys/types.h> where needed, it does not belong in config.h.
Remove <stdio.h> from config.h; if it is missing somewhere, it should
be added, but i cannot find a *.c file where it is missing.
