Exotic game engine using a tech stack of C + SDL + Lisp + Emscripten

The project name refers to the breed of long-haired grey cat.

Some git tricks were used to create this repo. It is overkill, but I wanted the full source of the tools and libs in the tech stack to be available as part of the project, for posterity's sake.

Dependency projects were added as remotes:

git remote add tinycc http://repo.or.cz/tinycc.git
git remote add femtolisp https://github.com/JeffBezanson/femtolisp.git
git remote add sdl https://github.com/spurious/SDL-mirror.git

The remotes were fetched:

git fetch tinycc
git fetch femtolisp
git fetch sdl

Branches were created:

git checkout -b tinycc tinycc/master
git checkout -b femtolisp femtolisp/master
git checkout -b sdl sdl/master
git checkout master

Subdirectories were added:

git read-tree --prefix=remote/tinycc tinycc
git read-tree --prefix=remote/femtolisp femtolisp
git read-tree --prefix=remote/sdl sdl

And of course committed (one at a time):

git checkout -- .
git commit

Hacks needed to compile are noted here in brief, gorey details are in the repo history.

• Some customizations were made in remote/femtolisp -- Makefile set CC = tcc -- llt/dtypes.h if defined TINYC then define SIZEOF_POINTER 8 -- llt/utils.h if defined TINYC then define ARCH_X86 and CPU 686
• MinGW libs and includes had to be added to TinyCC -- winsock2.h copied from gcc/include to tinycc/include
• "unknown constraint t" bug in math.h -- fix to i386-asm.c, patch found here

Although building with TinyCC is the goal, building with gcc should also be supported.

For Windows users, MinGW + MSYS is a good setup for this.
