Prevent Perl from introducing a possibly-incompatible definition of type

tglsfdc · tglsfdc · commit f608f3b87b9f · 2007-11-22T17:47:28.000Z
"bool" into plperl.c.  This has always been a hazard since Perl allows a
platform-specific choice to define bool as int rather than char, but
evidently this didn't happen on any platform we support ... until OS X 10.5.
Per report from Brandon Maust.

Back-patch as far as 8.0 --- a bit arbitrary, but it seems unlikely anyone
will be trying to port 7.x onto new platforms.
