Make these changes to ostack.h & opdef.h
GS 2.5 will compile OK, on SVR4. Ignore the compiler warnings.
If GS doesn't run, then recompile without the -O flag.
There are several optimizer bugs in the stock SVR4 compiler, which may not
be fixed in your compiler.



opdef.h
--------------------------------------------------
60c60
< typedef const op_def _ds *op_def_ptr;
---
> typedef /*const*/ op_def _ds *op_def_ptr;
--------------------------------------------------

ostack.h
--------------------------------------------------
30c30
< typedef const ref _ds *const_os_ptr;
---
> typedef /*const*/ ref _ds *const_os_ptr;
--------------------------------------------------
Hope this helps.

Gary.
