+ Backport GCPRO fix from trunk (Bug#13650).
+ The bug was reported for AIX before today's changes.
+ I reproduced the problem on Fedora 17 x86-64 when setting
+ GC_MARK_STACK by hand, and I presume it occurs with default
+ configurations on HP-UX and Unixware.
+ Trunk fix on 2013-01-14 by Dmitry Antipov <dmantipov@yandex.ru>:
+ Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
+ * eval.c (eval_sub): Protect `form' from being GCed before its
+ car and cdr becomes protected with the backtrace entry.
+
Fix AIX port (Bug#13650).
* lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
