[parisc-linux] PATCH: build gcc/gcc/depedence.c w/HPUX ANSI C

[Grant Grundler]

Hi folks,
I work on the parisc-linux port and was trying to build binutils/gcc
on an HP-UX 11 system. HP-UX ansic didn't like enum direction_type[][]
or int[][] constructs.  It complained with:
cc: "/linux/pa32/gcc/gcc/dependence.c", line 199: error 1501: Only the first
	dimension of an array may be omitted.

I've been told GCC refuses to compile the same thing with:
	x.c:1: warning: array `i' assumed to have one element
	x.c:1: storage size of `i' isn't known

This is probably not exactly the right fix but at least I can
build a binary now. I haven't tested the resulting binary.

thanks,
grant

I believe this was recently fixed in the mainline source:

2000-08-23  Alexandre Oliva  <aoliva@redhat.com>

        * dependence.c: Replace `[][]' with `[][MAX_SUBSCRIPTS]'.
