** 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; }
**
