No, it's 32 bits on that platform.

I'm not seeing that problem on Solaris 10 sparc with Oracle Developer Studio 
12.6 (a.k.a. Sun Studio). I built Bison 3.4.2 as follows:

export 
PATH=/usr/bin:/usr/sbin:/usr/ccs/bin:/r/share1/src/developerstudio12.6/bin
./configure M4=/usr/sfw/bin/gm4

where the Oracle compiler was installed in /r/share1/src/developerstudio12.6. 
How did you build Bison?

Also, what's the output of 'cc -E' on the following input, when you use your 
compiler with the same flags that you used to build Bison?

#include <inttypes.h>
#include <stdint.h>
#include <limits.h>
!(INT_MIN == INT32_MIN && INT_MAX == INT32_MAX)

For me, the output ends like this:

!( ( - 2147483647 - 1 ) ==  ( - 2147483647 - 1 ) &&  2147483647 ==  ( 
2147483647 ))
