bad compiler generated code?

[Sean McNeil]

I'm recompiling firefox right now and I get a whole bunch of the
following:

{standard input}:766: Warning: indirect jmp without `*'
{standard input}:816: Warning: indirect jmp without `*'
{standard input}:950: Warning: indirect jmp without `*'
{standard input}:999: Warning: indirect jmp without `*'
{standard input}:1547: Warning: indirect jmp without `*'
{standard input}:1597: Warning: indirect jmp without `*'
{standard input}:1783: Warning: indirect jmp without `*'
{standard input}:4021: Warning: indirect jmp without `*'

this happens on quite a number of C++ source files.  Looks like the
compiler is generating some bad assembly.

Cheers,
Sean
