 __builtin_va_list is a builtin type, not a macro.  Much like how "int" is
 not a macro... GCC will provide it.

>Description:
The test file test.c has one line:
  #include  <stdio.h>.
When the above file is pre-processed to produce testout using the command:
  cc -E test.c>testout.
The testout contains the following statement:
   typedef __builtin_va_list __gnuc_va_list
without any definition of __builtin_va_list. It appears that __builtin_va_list is generated by gcc but is not written to testout. This creates a problem for pre-processor that analyses the output file. Is there an option like -dM that will output all macros?
