problems compiling ORBit

[jgauthier elnino monad net]

I'm running on a solaris x86 machine (solaris 7) with egcs 1.0.3.

if looks like it compiles for awhile and then when it runs orbit-idl
on a file called interface_repository.idl it comes back with a syntax
error and then says
*** WARNING ***: parse error of interface_reposity.idl failed

any advice would be great!
