Sorry, I did not know that. For record, I am not a software
engineer. I am a hardware professional. And I needed 64-bit emacs
to read big files. I do use gcc -m64 for building my emacs. I try
building 64-bit emacs from emacs CVS almost once a week. Never
faced a problem.
I think I first successfully built 64-bit emacs some three months
back. That was the time when our sys-admin upgraded my sparc
machine to solaris 2.8. Our sys-admin is on leave, and I do not
know a way to get patch information on my system. I believe he
installed just the recommended patches from Sun.
So I have been compiling and running 64-bit emacs versions 21.X
and 21.3.50 on my solaris 2.8 for the past three months now
without any issue. The only issue I face is when I set my display
to a linux system, and launch 64-bit emacs on that display, emacs
dumps core. 32-bit solaris emacs compiles work fine.
I am sure that my emacs is 64-bit because ....
1. I use gcc -m64 to compile that.
2. I am able to open BIG files (200MB and more) with this
emacs. 32-bit emacs gives "Maximum buffer size exceeded" for
the same files.
3. I had to compile 64-bit versions of all the required
libraries. And my emacs is linked to 64-bit versions of sun
libraries. here is the ldd output ....

Well file does say that it is 64-bit version.

I am not competent to comment on these. The first time I
compiled 64-bit emacs was sometimes in oct 2002. RMS had put
a request on the emacs-pretesters list for testing on 64 bit
machines. At that time, I could compile emacs. I could even
run it with "emacs -nw". X11 emacs used to dump core. It
seemed to be some openwin internal error. I had reported
all this on the emacs-pretesters list.
Now I work for a different organization. And 64-bit emacs
compiles have been running fine since last 3 months. I use
64-bit emacs for almost everything (including gnus etc.)

I do use sun ld. I do not know how to check for which
malloc I am using. Should I send you the config.log file??
