 * Version 2.x, Copyright (C) 2001, Paul Marquess.
 * Version 1.x, Copyright (C) 1999, Kenneth Albanowski.
 * This code may be used and distributed under the same license as any
 * version of Perl.
 * 
 * This version of ppport.h is designed to support operation with Perl
 * installations back to 5.004, and has been tested up to 5.8.1.
 *
 * If this version of ppport.h is failing during the compilation of this
 * module, please check if a newer version of Devel::PPPort is available
 * on CPAN before sending a bug report.
 *
 * If you are using the latest version of Devel::PPPort and it is failing
 * during compilation of this module, please send a report to perlbug@perl.com
 *
 * Include all following information:
 *
 *  1. The complete output from running "perl -V"
 *
 *  2. This file.
 *
 *  3. The name & version of the module you were trying to build.
 *
 *  4. A full log of the build that failed.
 *
 *  5. Any other information that you think could be relevant.
 *
 *
 * For the latest version of this code, please retreive the Devel::PPPort
 * module from CPAN.

/*
 * In order for a Perl extension module to be as portable as possible
 * across differing versions of Perl itself, certain steps need to be taken.
 * Including this header is the first major one, then using dTHR is all the
 * appropriate places and using a PL_ prefix to refer to global Perl
 * variables is the second.
 *
 */


/* If you use one of a few functions that were not present in earlier
 * versions of Perl, please add a define before the inclusion of ppport.h
 * for a static include, or use the GLOBAL request in a single module to
 * produce a global definition that can be referenced from the other
 * modules.
 * 
 * Function:            Static define:           Extern define:
 * newCONSTSUB()        NEED_newCONSTSUB         NEED_newCONSTSUB_GLOBAL
 *
 */
 

/* To verify whether ppport.h is needed for your module, and whether any
 * special defines should be used, ppport.h can be run through Perl to check
 * your source code. Simply say:
 * 
 *    perl -x ppport.h *.c *.h *.xs foo/bar*.c [etc]
 * 
 * The result will be a list of patches suggesting changes that should at
 * least be acceptable, if not necessarily the most efficient solution, or a
 * fix for all possible problems. It won't catch where dTHR is needed, and
 * doesn't attempt to account for global macro or function definitions,
 * nested includes, typemaps, etc.
 * 
 * In order to test for the need of dTHR, please try your module under a
 * recent version of Perl that has threading compiled-in.
