+** Description: Definitions of NSPR's basic types
+**
+** Prototypes and macros used to make up for deficiencies that we have found
+** in ANSI environments.
+**
+** Since we do not wrap <stdlib.h> and all the other standard headers, authors
+** of portable code will not know in general that they need these definitions.
+** Instead of requiring these authors to find the dependent uses in their code
+** and take the following steps only in those C files, we take steps once here
+** for all C files.

+** MACROS:      PR_EXTERN
+**              PR_IMPLEMENT
+** DESCRIPTION:
+**      These are only for externally visible routines and globals.  For
+**      internal routines, just use "extern" for type checking and that
+**      will not export internal cross-file or forward-declared symbols.
+**      Define a macro for declaring procedures return types. We use this to
+**      deal with windoze specific type hackery for DLL definitions. Use
+**      PR_EXTERN when the prototype for the method is declared. Use
+**      PR_IMPLEMENT for the implementation of the method.
+**
+** Example:
+**   in dowhim.h
+**     PR_EXTERN( void ) DoWhatIMean( void );
+**   in dowhim.c
+**     PR_IMPLEMENT( void ) DoWhatIMean( void ) { return; }
