The current version of SDL is 2.0.3. All new releases of distributions contain
this library already. Current Linux distributions and OpenBSD even backporting
patches from Mupen64Plus 2.1 repo to use SDL 2. Android and other mobile
platform don't have support for legacy SDL 1.2.
People like Anthony J. Bentley and Riley Labrecque already requested
a new release of Mupen64Plus 2.1 with SDL2
The *.d depends files for make just list the files used when building an
object file. Removing a file listed in such a dependency file causes make to
search for a way to recreate it. This usually cannot work because these files
aren't autogenerated.
The gcc option -MP can be used to generate empty rule for these files. Removing
a file in a dependency list will then execute this empty rule and continue with
the execution of the creation of the object file. This compilation process will
then automatically correct the dependency file.
It is easier for a user to keep the old SDL1.2 values for the keys in the
config instead of converting them by hand. This is extreme important when the
default (automatic) config is used.
n.pepinpe requested in #540 to allow overwriting the automatically searched
CFLAGS and LIBS for used libraries. This should allow distributors to set the
build configuration without patching the makefile. This is important for
systems were pkg-config or sdl-config aren't normally used.

The GCC introduced Link-time optimization in GCC 4.5 (2010-04-14). This should
be long enough available that interested users have upgraded to a compiler
supporting it.
The MSVC project already enabled WholeProgramOptimization since a long time.
Enabling it by default in GCC seems to be equally valid.
The GCC manual states for different parameters that the options for compilation
must also be used when linking. The options for compilation are stored in
CXXFLAGS and added to LINK.o to fix the behavior.
Option which need this are for example -fPIC/-fPIE or -flto.
Some linker on different platforms don't handle the garbage collection
correctly and create extreme bloated binaries. Therefore, leave it to the user
to enable this feature or not.
