According to the ANSI specification, types and typedefs should both be
able to exist interchangeably in function prototypes, and the
Microsoft C and QuickC compilers do allow function prototypes to
include typedefs in the parameter type list. However, the compilers do
not allow parameters to functions or function pointers within the type
list to have typedef'd parameters. For example, given the following
declarations

   typedef int FirstType;
   typedef int SecondType;
   int foo( int, FirstType, int *( SecondType ) );

the compilers have no problem with "FirstType" but they will halt with
an error when they reach "SecondType".

Although the syntax is correct according to ANSI, the compilers
incorrectly generate the following error when they encounter the
second typedef:

   error C2061: syntax error : identifier 'SecondType'

Microsoft has confirmed this to be a problem in C versions 5.10, 6.00,
and 6.00a and QuickC versions 2.00, 2.01, 2.50, and 2.51 (buglist2.00,
buglist2.01, buglist2.50, and buglist2.51). We are researching this
problem and will post new information here as it becomes available.
