Summary: Internal error: validateLink failed in SPEC_BLEN

Initial Comment:
Double dereference on an array of pointers addressing a bitfield causes an internal error.

See code below. Compiled with:
$ sdcc/bin/sdcc  -mpic16 -p18f2550  -obitfield bitfield.c
Internal error: validateLink failed in SPEC_BLEN(operandType(result)) @ /home/sdcc-builder/build/sdcc-build/orig/sdcc/src/pic16/gen.c:8202: expected SPECIFIER, got DECLARATOR

Versions tried:
- 2.8.0 (Fedora 9 stock)
- sdcc-snapshot-i386-unknown-linux2.5-20090427-5436.tar.bz2

--- begin code bitfield.c ---
struct bitfield {
	unsigned bit:1;
} *bla[1];

void func(void)
{
	if(bla[0]->bit)
		bla[0]->bit = 0;
}
--- end code bitfield.c ---
