[Bug c/14963] New: Unknown types cause ICE in function declarations

[ekarttun at cs dot helsinki dot fi]

The following code causes the cvs HEAD of 2004-04-11 to crash:

X Y(Z);

With gcc 3.3.3 it produces a proper error.

The output is the following:

e@rei:~/objc/gcc-work/libobjc-fixes$ gcc crash.c 
crash.c:1: error: syntax error before "Y"
crash.c:1: warning: parameter names (without types) in function declaration
crash.c:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

Confirmed a regression, most likely caused by Zack's c-decl rewrite.

This is weird as I am able to reproduce it on i686-pc-linux-gnu but not powerpc-apple-darwin.
