Failing test case

Doh!  I hit the wrong key.

There appears to be a problem with function inlining corrupting the range of
C's enumerated types.  This currently causes a bootstrap failure on Tru64
alphaev67-dec-osf5.1.  The attached testcase is reduced from GCC's mips-tdump.c
that demonstrates the problem on other platforms, including i686-pc-linux-gnu.

When compiled -O3, we currently generate the error messages:
foo3.i: In function `print_symbol':
foo3.i:413: warning: case label value 32 exceeds maximum value for type
foo3.i:450: warning: case label value 64 exceeds maximum value for type

This problem does not occur compiling the same file at -O2.   The original
from which this testcase is derived declared print_symbol and sc_to_string
as static which triggered the problem at -O2.
