[perl #27007] ppport.h doesn't work with threaded 5.6.x + PERL_NO_GET_CONTEXT

This is a bug report for perl from steve.hay@uk.radan.com,
generated with the help of perlbug 1.34 running under perl v5.8.2.


-----------------------------------------------------------------

If you create an XS module using ppport.h generated by Perl 5.8.2 then 
it doesn't build
under a threaded Perl 5.6.x if the XS file says "#define 
PERL_NO_GET_CONTEXT".

To reproduce this, type the following using Perl 5.8.2:

    h2xs -n Foo -b 5.6.0

and then edit the Foo.xs file to add

    #define PERL_NO_GET_CONTEXT

as the first line in the file.

Now try to build that "Foo" module using a threaded Perl 5.6.1.  On my 
WinXP/MSVC system
this produces the following errors:

=====
ppport.h(633) : error C2065: 'my_perl' : undeclared identifier
ppport.h(633) : warning C4047: 'function' : 'struct interpreter *' 
differs in levels of indirection from 'int '
ppport.h(633) : warning C4024: 'Perl_scan_hex' : different types for 
formal and actual parameter 1
ppport.h(648) : warning C4047: 'function' : 'struct interpreter *' 
differs in levels of indirection from 'int '
ppport.h(648) : warning C4024: 'Perl_scan_oct' : different types for 
formal and actual parameter 1
ppport.h(663) : warning C4047: 'function' : 'struct interpreter *' 
differs in levels of indirection from 'int '
ppport.h(663) : warning C4024: 'Perl_scan_bin' : different types for 
formal and actual parameter 1
NMAKE : fatal error U1077: 'cl' : return code '0x2'
Stop.
=====

The errors go away if the PERL_NO_GET_CONTEXT define is removed, but the 
module should
be more efficient with it, shouldn't it?

The Devel::PPPort version in 5.8.2 is 2.009.  I've also tried version 
2.011 from
the current maint-5.8, with the same results.

An earlier version of Devel::PPPort (2.0002, distributed with Perl 
5.8.0) worked fine.
