hi Ken;

Yes, the above works, but the c2ada uses typedefs and it includes
_Bool in there, and that is where the problem occur.

I've just reduced this problem to this simple example to help
illustrate it:

gcc -c il.h
il.h:5: error: expected identifier before '_Bool'


$ cat il.h

#include <stdbool.h>

typedef enum {
        _Bool,    /* cvt to Boolean, Ada only, unary */
        _UnBool,  /* cvt bool->int,  Ada only, unary */
} node_kind_t;

$ gcc -c -std=c99 il.h
il.h:5: error: expected identifier before '_Bool'
$ gcc -c -ansi il.h
il.h:5: error: expected identifier before '_Bool'
$ gcc -c -std=gnu89 il.h
il.h:5: error: expected identifier before '_Bool'

nabbasi@my-desktop:~/try$ gcc --version
gcc (GCC) 4.1.3 20070403 for GNAT GPL 2007 (20070402)

Could you please try the above on your system? may be my gcc
installation is bad.
I am using Ubuntu

nabbasi@my-desktop:~/try$ uname -a
Linux my-desktop 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007
