+mdate	12 Apr 2001

+port	all
+Checking in perl5-base/patches/patch-ag: 1.2 : 1 : 999
+descr
+	The Xerces-Perl module is implemented as a shared object. It needs 
+	some symbols from libgcc.a, such as __eh_alloc. It's not possible
+	to link the xerces-P shared object with libgcc.a, because libgcc.a
+	is not compiled with -fPIC. Hence we need to have the missing 
+	symbols in the Perl executable. 
+	This hack includes the whole libgcc.a in the Perl executable, and
+	links with c++ so that some mandatory symbols such as __pure_virtual 
+	are also included. It should go away with GCC-3.0, or if we make a
+	libgcc.so on day.

+file	devel/pth/Makefile	: 1.37 : 20 : 22

+	OpenOffice segfaults after some time in the pthread library with a 
+	completely thrashed stack. Removing optimization when building
+	pth (-O0) avoids this problem.

+cdate 	26 Feb 2002
+who	mrauch
+file	misc/openoffice/patches/patch-dj
+file	misc/openoffice/patches/patch-dk
+descr	Using versioned symbols the special symbol _etext can end up
+	in the shared library with a junk value for the version string
+	instead of "0" for no version. Sometimes it is sufficient to 
+	reorder the -l flags on the link line but the general hack is to
+	disable versioned symbols.

+hack	sparc64-kth-krb

+file	security/kth-krb4/Makefile
+descr	This package hangs when compiling one of the files with the
+	compiler that comes with 1.5ZC. The compiler needs to be killed
+	manually - the package is marked as interactive on sparc64 for
+	that reason.
