+ *
+ * Automatically Created by Devel::PPPort on Fri Feb 28 15:36:17 2003
+ *
+ * Do NOT edit this file directly! -- Edit PPPort.pm instead.
+ *
+ * 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 5.8.0.
+ *
+ * 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

+ * produce a global definition that can be referenced from the other
+ * modules.

+/* 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.
