What was the crocky stuff in the X headers?
from X11/Intrinsic.h:
...
typedef char Boolean;
...
#if NeedWidePrototypes
#define Boolean int
#define Dimension int
#define KeyCode int
#define Position int
#define XtEnum int
#endif /* NeedWidePrototypes */
...
extern void XtAddEventHandler(
#if NeedFunctionPrototypes
Widget /* widget */,
EventMask /* eventMask */,
Boolean /* nonmaskable */,
XtEventHandler /* proc */,
XtPointer /* closure */
#endif
);
...
#if NeedWidePrototypes
#undef Boolean
#undef Dimension
#undef KeyCode
#undef Position
#undef XtEnum
#endif /* NeedWidePrototypes */
This method just kept the prototypes looking good. If the types are
also used as return values, I use the uglier form:
extern XtGeometryResult XtMakeResizeRequest(
#if NeedFunctionPrototypes
Widget /* widget */,
#if NeedWidePrototypes
/* Dimension */ int /* width */,
/* Dimension */ int /* height */,
#else
Dimension /* width */,
Dimension /* height */,
#endif /* NeedWidePrototypes */
Dimension* /* replyWidth */,
Dimension* /* replyHeight */
#endif
);
if we ever wanted to add the indirection, all we would have to do would
be to replace libkdb.a with a version that had the extra code in it.
Fine; at least there *is* some rationale :-)
