>Environment:
gdb and the test program were both compiled with gcc 2.96 and Linux sumatra.ca.metsci.com 2.4.18-17.7.xsmp #1 SMP Tue Oct 8 12:37:04 EDT 2002 i686 unknown

i686-pc-linux-gnu"...Using host libthread_db library "/lib/libthread_db.so.1
>Description:
When I tell gdb to print the variable, it says <incomplete type>.  I
believe that I have given gdb complete information about the type since
I compiled all of the source code with -g.

I expected it to print a number instead of <incomplete type>.
>How-To-Repeat:
struct blob {
    typedef enum {} alias;
};

int main() {
  blob::alias variable;
}
