LONG_MAX is not defined properly in 2.95.2's limits.h

Hi.  It appears that LONG_MAX is not defined properly in

  ./lib/gcc-lib/sparc-sun-solaris2.7/2.95.2/include/limits.h

The definition looks like 
   /* Minimum and maximum values a `signed long int' can hold. 
     (Same as `int').  */ 
   #ifndef __LONG_MAX__ 
   #if defined (__alpha__) || defined (__sparc_v9__) || defined (__sparcv9) 
   #define __LONG_MAX__ 9223372036854775807L 
   #else 
   #define __LONG_MAX__ 2147483647L 
   #endif /* __alpha__ || sparc64 */ 

Now if we use gcc 2.95.2 on a ultra sparc machine with 
   -mcpu=ultrasparc

Then, __sparc_v9__ will be defined and thus the above
assumed that we are in 64-bit mode which would be bad if
we are running in 32-bit mode.

NOTE that gcc 2.8.1 appears to have this setup properly.

  #ifndef __LONG_MAX__
  #if defined (__alpha__) || (defined (__sparc_v9__) && defined (__arch64__))
  #define __LONG_MAX__ 9223372036854775807L
  #else
  #define __LONG_MAX__ 2147483647L
  #endif /* __alpha__ || sparc64 */

Note the "&& defined (__arch64__)" conditional to be sure we 
don't always use the 64-bit version under ultra-sparc.
