64 Bit Apache httpd on Solaris

[Kevin.Friswell@xxxxxxxxxxxxxxx]

The Goal
A 64bit
httpd executable on Solaris 5.10,  (independent of the "out of
the box Solaris Apache server).

(isainfo –v
        64-bit
sparcv9 applications
         
      fmaf vis2 vis popc
        32-bit
sparc applications
         
      fmaf vis2 vis popc v8plus div32 mul32 )

Current Postion
A 32bit
httpd executable on Solaris 5.10.  -->
        /usr/local/apache2/bin
> file httpd
        httpd:
         ELF 32-bit MSB executable SPARC Version
1, dynamically linked, not stripped

Steps Taken
1)        Download
 httpd-2.2.17.tar.gz and copy to Solaris server.  (http://httpd.apache.org/download.cgi)
        Nothing
I could find at the download site about a 32bit/64bit download - so I assume
this is 
        determined
at configuration/compilation time and there's just the one download for
both setups.

2)        Follow
instructions in httpd-2.2.17\INSTALL document.  Install into /usr/local/apache2
       
        Nothing
in the instructions matching search strings "64", "32"
or "bit".
        Check
http://httpd.apache.org/docs/2.2/install.html
 -- same result
        Run
httpd-2.2.17 > ./configure --help  ...  no sign of anything
in the help options about configure 32 or 64 bit. 

3)        Search
apache.org website - some instruction about Win64 but nothing useful for
Solaris.
        Google
  -  used key words/phrases such as  "compiling 64
bit solaris", "Apache 64 bit Solaris",  "Apache
64bit CFLAGS"
        "CFLAGS
syntax"

        I
found a few reasonable matches, but at best the sites either give me a
better general understanding
        of
this stuff, or they show some compile options that result in errors, (not
much use).

Where to go from here
Obviously this stuff is not my primary
area of expertise, but my hunch is that this "problem" might
have a fairly simple solution - perhaps
a compiler option or something, but
be stuffed if I can find it. If someone would be kind enough to help me
along a bit with this it would be 
greatly appreciated.

Cheers All
