Good point, btw :
This is done in the pnet itself :

"uint" is defined in sys/types.h and as a field in ffi.h,

cheers,

# 148 "/usr/include/sys/types.h" 2 3
[....]
typedef unsigned int uint;

# 363 "../libffi/include/ffi.h"
typedef union {
  int sint;
  unsigned int uint_value; /*MDUPONT : was uint, bug number 
https://savannah.gnu.org/bugs/?func=detailbug&bug_id=4689&group_id=353 */
  float flt;
  char data[4];
  void* ptr;

Summary:  [PNET/C] [PARSER/DATATYPE] Problem with using a field name that is 
already a datatype. 

Original Submission:  The following snippet of code shows you a bug in the 
typedef handling system. You need to look for the field before resolving the 
typedef.
###########################################
##########################################
typedef unsigned int datatype;
typedef union {
  unsigned int datatype;
  void* ptr;
} my_union;


/* 

cscc test_local_name.c
test_local_name.c:3: syntax error, unexpected ';' at or near `;'
test_local_name.c:5: syntax error, unexpected '}' at or near `}'

*/

Fix committed to CVS - 10 Aug 2003

BTW, don't do this - it is bad coding practice and
probably won't work on non-gcc C compilers.
