8	* Version 2.x, Copyright (C) 2001, Paul Marquess.
9	* Version 1.x, Copyright (C) 1999, Kenneth Albanowski.
10	* This code may be used and distributed under the same license as any
11	* version of Perl.
12	*
13	* This version of ppport.h is designed to support operation with Perl
14	* installations back to 5.004, and has been tested up to 5.8.1.
15	*
16	* If this version of ppport.h is failing during the compilation of this
17	* module, please check if a newer version of Devel::PPPort is available
18	* on CPAN before sending a bug report.
19	*
20	* If you are using the latest version of Devel::PPPort and it is failing
21	* during compilation of this module, please send a report to perlbug@perl.com
22	*
23	* Include all following information:
24	*
25	* 1. The complete output from running "perl -V"
26	*
27	* 2. This file.
28	*
29	* 3. The name & version of the module you were trying to build.
30	*
31	* 4. A full log of the build that failed.
32	*
33	* 5. Any other information that you think could be relevant.
34	*
35	*
36	* For the latest version of this code, please retreive the Devel::PPPort
37	* module from CPAN.

42	* In order for a Perl extension module to be as portable as possible
43	* across differing versions of Perl itself, certain steps need to be taken.
44	* Including this header is the first major one, then using dTHR is all the
45	* appropriate places and using a PL_ prefix to refer to global Perl
46	* variables is the second.
47	*

51	/* If you use one of a few functions that were not present in earlier
52	* versions of Perl, please add a define before the inclusion of ppport.h
53	* for a static include, or use the GLOBAL request in a single module to
54	* produce a global definition that can be referenced from the other
55	* modules.

63	/* To verify whether ppport.h is needed for your module, and whether any
64	* special defines should be used, ppport.h can be run through Perl to check
65	* your source code. Simply say:
66	*
67	* perl -x ppport.h .c .h .xs foo/bar.c [etc]
68	*
69	* The result will be a list of patches suggesting changes that should at
70	* least be acceptable, if not necessarily the most efficient solution, or a
71	* fix for all possible problems. It won't catch where dTHR is needed, and
72	* doesn't attempt to account for global macro or function definitions,
73	* nested includes, typemaps, etc.
74	*
75	* In order to test for the need of dTHR, please try your module under a
76	* recent version of Perl that has threading compiled-in.
