Thanks for mentioning the problems.

I built and and ran the Bison tests with Bison HEAD on Solaris 10 sparc 
with Studio 12.3 (which supports C89 and C++03 by default, if I'm not 
mistaken) and found one failure that was definitely a C++ compiler bug, 
another one where I wasn't sure (I don't use C++ much) but a simple 
workaround is available, two failures due to Solaris 10 /usr/bin 
programs not quite conforming to POSIX, three integer overflow bugs 
(ouch!), and two portability bugs where Bison was incorrectly assuming 
partial support by Studio for C99 and for GCC __attribute__ syntax. I 
installed the attached patches into Bison HEAD to fix everything but the 
C++ compiler bug, which I just now reported separately 
<https://lists.gnu.org/r/bug-bison/2019-10/msg00058.html>.

If you build Bison HEAD (which requires special tools) I suspect that 
almost all the problems are now fixed on Solaris x86 as well, but I 
haven't checked this.
