I've tripped over the same problem some time ago, but didn't have time to
report or provide a fix.  The problem is that IRIX 6.5.17 and 6.5.18
introduced a definition of socklen_t in <sys/socket.h>.  libjava assumes
that if socklen_t is defined, it can be used e.g. as the type of accept's
last arg.  This is wrong here, since IRIX provides several different
definitions of accept, with differing types:

#if _NO_XOPEN4 && _NO_XOPEN5
/* Std BSD4.3/SGI */
extern int accept(int, void *, int *);

#if _ABIAPI
/* BB3.0 is XPG compliant but can't use hidden names */
extern int accept(int, struct sockaddr *, size_t *);

#else
/* this is normal XPG */
extern int __xpg4_accept(int, struct sockaddr *, size_t *);

So socklen_t should match those, but doesn't, leading to the compilation
failure observed.  This is a known bug (Bug Id 864477), to be fixed in the
upcoming 6.5.19, but not for 6.5.1[78].

I meant to fix the current definition via fixincludes to read like this:

/*
 * socklen_t type definition
 */
#ifndef _SOCKLEN_T
#define _SOCKLEN_T
#if _NO_XOPEN4 && _NO_XOPEN5
typedef int socklen_t;
#else
typedef size_t socklen_t;
#endif /* _NO_XOPEN4 && _NO_XOPEN5 */
#endif /*_SOCKLEN_T */

Unfortunately, I haven't found any time to do so.  I'll probably wait for
6.5.19 (to be released in a few days) to check their definition to make
sure I don't do anything incompatible for 6.5.1[78] and don't break 6.5.19
either.
