Subject: UPDATED: Building 1.8.6-p36 with Sun Studio 12 compiler

All -
    I have resolved most of the problems encountered during "make
check"; it seems the test runs do not honor LD_LIBRARY_PATH, so I had
to symlink the libraries for openssl, gdbm and ncurses to /lib, and
then my results look like this

	    Finished in 73.679603 seconds.

          1) Failure:

So it appears that most of the compiler warning messages are in fact
harmless. I would like to understand though why "--enable-pthread"
causes the backtrace error in eval.c:

eval.c
"eval.c", line 4482: warning: statement not reached
"eval.c", line 4517: warning: statement not reached
"eval.c", line 4644: warning: statement not reached

"eval.c", line 6251: identifier redeclared: backtrace
         current : static function() returning unsigned long
         previous: function(pointer to pointer to void, int)

"eval.c", line 8612: warning: loop not entered at top

"eval.c", line 12446: warning: statement not reached
"eval.c", line 12818: warning: statement not reached
cc: acomp failed for eval.c
gmake: *** [eval.o] Error 2

It seems to modify the includes such that /usr/include/execinfo.h gets
included, when without the "--enable-pthread" it doesn't (or some
other define "hides" the definition of backtrace).
