+Subject: [PATCH 1/5] Strip the .note.gnu.property section for the mbr
+
+This section is added since binutils Debian version 2.31.1-2 and causes mbr.bin
+to grow in size beyond what can fit into the master boot record.

+Subject: [PATCH 2/5] Force the linker to put all sections into a single
+ PT_LOAD segment
+
+This is required when using binutils >= 2.31 which writes two PT_LOAD segments
+by default. This is not supported by the wrapper.c script used to convert the
+shared object into an elf binary.

+Subject: [PATCH 3/5] GCC-10 compatibility patch
+
+* Add `-fcommon` to most gcc invocations to allow duplicate definitions
+* __builtin_strlen is not really a "builtin" an implementation still
+  needs to be provided (source:
+  https://bugzilla.suse.com/show_bug.cgi?id=1166605#c5). Work around the
+  issue by supplying an inline function. The strlen function added to
+  dos/string.h was copied from com32/lib/strlen.c.
