I got the following compile error:

The declaration of u_char in /usr/include/sys/types.h is:

<--  snip  -->

...
#if !defined(_POSIX_SOURCE) && !defined(_XOPEN_SOURCE)
typedef unsigned char   u_char;
typedef unsigned short  u_short;
typedef unsigned int    u_int;
typedef unsigned long   u_long;
...

<--  snip  -->


The compilation breaks because of the unconditional definition of
_XOPEN_SOURCE in configure.in .
