autoconf 2.5, 2.13, and Vim

[Charles E. Campbell]

Hello!

In attempting to compile Vim 6.0ai and Vim 6.0aj on my
Sgi (o/s: Irix 5.3), the configure process produces
wrong results for several types using autoconf 2.50.
Note that Bram Moolenaar used to use autoconf 2.13 which
didn't exhibit this problem.

 ---------------------------------------------------------------------
#define mode_t int
#define off_t long
#define pid_t int
#define size_t unsigned
#define ino_t long
#define dev_t unsigned
 ---------------------------------------------------------------------

These are all defined in <sys/types.h> using SGI's C compiler from
Irix 5.3.

The relevant portions of <sys/types.h>:
 ---------------------------------------------------------------------
#if (_MIPS_SZLONG == 32)
typedef unsigned long   mode_t;         /* file attrs */
typedef unsigned long   dev_t;          /* device type */
typedef long            uid_t;
typedef long            gid_t;
typedef unsigned long   nlink_t;        /* used for link counts */
typedef long            pid_t;          /* proc & grp IDs  */
typedef unsigned long   ino_t;          /* <inode> type */
#endif
...
#if !defined(_KERNEL) || defined(_STANDALONE)
typedef long            off_t;          /* byte offset type */
#else   /* !_KERNEL || _STANDALONE */
typedef __int64_t       off_t;          /* byte offset type */
#endif  /* !_KERNEL || _STANDALONE */
...
#if (_MIPS_SZLONG == 32)
typedef unsigned int size_t;
#endif
#if (_MIPS_SZLONG == 64)
typedef unsigned long size_t;
#endif
#endif /* !_SIZE_T */
 ---------------------------------------------------------------------


I've also enclosed a uuencoded and compressed copy of configure's output:
