From GCT 1.2:

GCT works on the OSF/1 Decstation (Mips chip).  The following change
was required to one GCT file:

> cc -O2  -I. -I. -I./config -c insn-emit.c
> cfe: Error: insn-emit.c, line 749: missing size for array 'emit_operand'
>    rtx emit_operand[0];
>  ------^
> cfe: Error: insn-emit.c, line 749: storage size for 'emit_operand' isn't known
>    rtx emit_operand[0];
>  ------^
> cfe: Warning: insn-emit.c, line 749: Must be an integer type greater than zero.
>    rtx emit_operand[0];
>  -------------------^
> *** Exit 1
> 
> { I changed the '0' to a '1'  and it built OK }

When running the test suite, there are spurious blank lines in the LOG
file.  These seem to come from the C compiler.  They're harmless.
