/* Define to 1 to build client libraries as thread-safe code.
   (--enable-thread-safety) */
#define USE_THREADS 1

So this seems to be the collision.

--enable-thread-safety is a new option for libpq - however this collides
with perl's use of the same macro.

I suspect that the right answer would be to change the name USE_THREADS
to PG_USE_THREADS for pg.

Quick and nasty work around patch:

--- plperl.c.7.4        Thu Sep  4 08:16:39 2003
+++ plperl.c    Mon Nov 17 23:07:05 2003

 #include "catalog/pg_proc.h"
 #include "catalog/pg_type.h"

+#undef USE_THREADS
 /* perl stuff */
 #include "EXTERN.h"
 #include "perl.h"

another fix would be to make plplerl use the explicit api.
