+Subject: [PATCH] Fix "`gcc_struct' attribute directive ignored" warnings
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Compilation for target architectures other than i386, x86_64 or PowerPC
+(e.g. ARM) caused multiple warnings like the following to appear:
+
+  doomdata.h:75:1: warning: ‘gcc_struct’ attribute directive ignored
+   } PACKEDATTR mapsidedef_t;
+   ^
+
+This was due to 'gcc_struct' being undefined for these architectures.
+Since that attribute was actually introduced by commit 87db726b9a9ae61ca
+to address the fact that -mms-bitfields became the default for GCC on
+Windows, limit it to that case.
+
+Upstream-status: accepted, not yet released.

+Subject: [PATCH] configure: fix --with-PACKAGE option checks
+
+Options of the form --with-PACKAGE[=yes] (e.g. --with-libpng), when
+passed to configure, were being treated as though --without-PACKAGE had
+been given.
+
+Although the intention is to have configure check and use PACKAGE by
+default if it's available, thus requiring the user to pass an option
+only if PACKAGE must NOT be used, there are times when the opposite
+might be desired (i.e. the user wants to indicate PACKAGE MUST be used).
+Moreover, allowing --with-PACKAGE and behaving as if --without-PACKAGE
+had been specified is in itself quite confusing.
+
+Fix that by testing the result of 'with_PACKAGE' in configure.ac and
+acting accordingly instead of blindly assuming a 'no'.

+Subject: [PATCH] opl: limit use of ioperm/inb/outb to x86 architecture
+
+The use of I/O ports in the Linux driver to directly control OPL chips
+is x86 specific and only really makes sense for x86-based PC's with
+compatible hardware.
+
+For some architectures (e.g. ARM), ioperm, inb and outb do exist and are
+detected by the configure script (via AC_CHECK_FUNCS(ioperm)), but their
+use is inappropriate in these cases and should be avoided.
+
+In some other scenarios, like when using a GNU toolchain + uClibc for
+PowerPC, the build even fails with the following error:
+
+  opl_linux.c:26:20: fatal error: sys/io.h: No such file or directory
+
+That is so because ioperm() is exported by uClibc and gets detected by
+configure, which enables the "Linux" driver via definition of
+HAVE_IOPERM, but in practice 'sys/io.h' is missing for ppc (inb/outb is
+not implemented, and the call to ioperm() would return EIO anyway).
+
+So, besides testing for HAVE_IOPERM, also test if either __i386__ or
+__x86_64__ are defined before enabling this OPL driver.
+
