Compiling a 64-bit gdb 7.7 on Solaris (8 to 11) with gcc fails in bfd:

cc1: warnings being treated as errors
/vol/src/gnu/gdb/gdb-7.7/bfd/cache.c: In function 'bfd_cache_max_open':
/vol/src/gnu/gdb/gdb-7.7/bfd/cache.c:85: error: comparison between signed and unsigned integer expressions

This is about

	  && rlim.rlim_cur != RLIM_INFINITY)

where <sys/resource.h> has

typedef unsigned long   rlim_t;
#define RLIM_INFINITY   (-3l)

While I've raised the issue with Oracle, the problem can easily be
avoided by casting RLIM_INFINITY to rlim_t, as the following patch does.

Ok for mainline?

	* cache.c (bfd_cache_max_open): Case RLIM_INFINITY to rlim_t.
