+** 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; }

+**
+** The 8-bit and 16-bit integer types can only be defined using char and
+** short. All platforms define the 32-bit integer types using int. So only
+** the 64-bit integer types could be defined differently.
+**
+** NSPR's original strategy was to use the "shortest" 64-bit integer type:
+** if long is 64-bit, then prefer it over long long. This strategy is also
+** used by Linux/glibc, FreeBSD, and NetBSD.
+**
+** Other platforms use a different strategy: simply define the 64-bit
+** integer types using long long. We define the PR_ALTERNATE_INT64_TYPEDEF
+** macro on these platforms. Note that PR_ALTERNATE_INT64_TYPEDEF is for
+** internal use by NSPR headers only. Do not define or test this macro in
+** your code.
+**
+** NOTE: NSPR can't use <stdint.h> because C99 requires C++ code to define
+** __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS to make all the macros
+** defined in <stdint.h> available. This strange requirement is gone in
+** C11. When most platforms ignore this C99 requirement, NSPR will be able
+** to use <stdint.h>. A patch to do that is in NSPR bug 634793.
