I agree that this isn't something to be solved by any compiler modification.

I would go back to Ralf's suggestion to uncomment
load64bit:2:wait:/etc/methods/cfg64
from your inittab file.  This simply allows 64-bit executables to run;
meanwhile your program can still be compiled and executed as a 32-bit
executable.
The "bind64" is actually the default binder (back-end to the 'ld' command)
if you are running on a 64-bit machine.
The distinction is that "bind64" itself is a 64-bit executable, but it
can be used to create either 32-bit or 64-bit executables, whichever you
requested.  It will create 32-bit executables by default.

Normally you don't even pay any attention to 'bind' (or 'bind64') because ld
runs it for you.  However, if you really don't want to allow 64-bit executables
to run, you could override the default binder.  When you do your compile,
whether it is with gcc or cc, add LDFLAGS="-Wl,-bbinder:/usr/ccs/bin/bind"
to tell 'ld' to use the other bind backend.
If you allow 64-bit binaries though, you wouldn't have to override this.
