When I run `./configure` on Solaris9 SPARC (64-bit), I get:

checking for gcc... gcc
checking for C compiler default output... configure: error: C compiler
cannot create executables

# isainfo -vk
64-bit sparcv9 kernel modules

Some notes of interest:
- the GCC compiler seems to be working fine, which I tested by compiling
"hello.c", as well as IPFilter (which doesn't use autoconf)
- this seems to happen only on 64-bit SPARC systems, and only with autoconf
(well DUH, since `./configure` is an autoconf generated script)
- GCC version is 3.3.3, installed from blastwave.org (along with the gcc3rt
package)

On Solaris9 x86 as well as Solaris9 SPARC 32-bit everything compiles fine!
WHAT IS GOING ON!?!

check config.log to see what happened

Make sure The C preprocessor is in your  path "cpp", its usually found 
in /usr/bin/cpp or /usr/local/bin/cpp.

   This sounds a lot like problems with paths.  My guess is that your 
path doesn't include the compiler or the binary uitls which sit in 
/usr/ccs/bin

That's the first thing I do.  Does "exit 77" sound descriptive?

Anyways, this was an idiot error type-a-deal: a .cshrc env file was
transported from Solaris9 x86 to Solaris9 SPARC. In it, there was a setting:

"setenv CFLAGS -march=i686 -D_REENTRANT".

I uncovered this almost by an accident. If that doesn't bust your compiler
on SPARC, nothing will.
