#739: Allow more specific foreign types
-------------------------------+--------------------------------------------
 Reporter:  syn                |       Owner:  felix
     Type:  enhancement        |      Status:  new  
 Priority:  minor              |   Milestone:  4.8.0
Component:  compiler           |     Version:  4.7.x
 Keywords:  ffi foreign types  |  
-------------------------------+--------------------------------------------
 Currently, typedefs cannot be used directly but have to be replaced by an
 approximated equivalent FFI type, e.g. {{{typedef unsigned int foo}}}
 would have to to be referred to as {{{unsigned-int}}} yielding some
 compiler warnings. Even worse: If the type is defined differently for
 different platforms, say, it might not work at all. My suggestion is to
 allow a similar construct like {{{(struct "foo")}}} to say {{{(unsigned-
 int "foo")}}}. With this the compiler would know what foreign type to use
 but insert the correct typedef name in the generated code.
