Subject: [9fans] zero length arrays in gcc

Hi all

nhc98 uses a few of

static unsigned startLabel[]={};

which is a zero length array. It appears that it uses this as
reference to calculate the correct pointer for a bytecode.

pcc does not allow this since zero lenth array is another gcc
extension. I tried declaring it as

static unsigned startLabel[];

The resulting bytecode can then be compiled however it will only
crash. I traced it a pointer that tries to read an unallocated section
in memory.

Is it possible emulate zero pointer in pcc??
