Merge pull request #88 from groessler/something_to_pull

rename libsrc/atari/tvtype.s to libsrc/atari/get_tv.s
Changed Makefile.inc handling.

It seems more appropriate to trigger the inclusion of Makefile.inc via $TARGET (instead of $SRCDIR). This is btw. more consistent with extzp.s inclusion which is triggered via $TARGET too.
Check out install of MinGW cross devel packages.
Maybe better when avoiding transition packages?
Just playing to maybe understand more...
The last one worked - why? What about this...
Fixed typo.
Check what we have.
Moving on...
One more...
Okay, binutils-mingw-w64-i686 seems to have to be listed explicitly.
Removed -std=c89.

Using `struct stat` and `%m` surely doesn't qualify for ISO C90.
First attempt of MinGW cross build.
Support both MinGW and MinGW-w64.
Removed by now obsolete pragmas.

The warnings in question are instead suppressed by command line options.
Have src/Makefile and libsrc/Make use disjoint work directories.

Building the clean target in src or libsrc should only delete stuff created by the make in those directories. Having both separated allows the Travis CI build to replace the native binaries with cross built binaries while keeping everything else.
Moved from VS2013 to MinGW(-w64).
Moved .PHONY below definitions it refers to.

I must admit that I don't understand why but obviously it is necessary to place .PHONY below the definition of variables it refers to - although those variables are recursively expanded ones! Not doing so made libsrc/Makefile build only three target libraries.
fix typo
fix indentation
