Can't get 'gcc' to work

On a SCO Unix system, the gcc command returns

gcc: syntax error at line 1: `)' unexpected

regardless of what else in on the command line.

Thus far I have added "INCLUDE=" and the path to stdio.h which only had an include statement to ast_stdio.h to my start up procedure.

I am trying to update some C programs we could compile a few years ago before a certain computer died, but am at a loss as to what to do next.

TIA

Sounds like gcc is a script executable which calls the real binary on your system. Perhaps it is being run in an incompatible shell.

where did you get gcc from and how did you unstall it.
