Small calculator for gp2x-f200 using the touchscreen

** WARNING ** 
I am not responsible if you are making wrong calculations with this program, 
especially since it has NOT been thoroughly tested.

So if you compute the size of the elements of the bridge next door 
and then it collapses, don't come to me ;-)

I hereby will take not responsability whatsoever for what you're doing with 
this program or the included sources, it may make your tv set explode or 
even kill your dog. You have been warned.

** END of WARNING **

INSTALLATION and USE
--------------------

- erase all files from the previous release if applicable

- drop somewhere the following files:
  fcalc.gpe 
  the directory fcalc that lies with it

- fire fcalc.gpe

COMPILING (not mandatory)
-------------------------

I use open2x
'make' to build up the gpe file
'./Make_linux' to buildup the Linux version (for testing)
some adjustments must be done to the files to fit with your environment

Hope you find this little program fun,
Flynn

dev notes:
 
In f/w 4.1.x, the touchscreen appears to have been fixed in the SDL library itself. BUT there is no way to dynamically link to this SDL lib and have the other libraries to behave properly (or to put it in a different way, I tried everything I could think of, and failed)

So, to make the touchscreen work along with the other libraries, I statically linked the project (to get all maths libs to work properly) but without the SDL libraries.
Then, to link dynamically the SDL libraries in this static project, I wrote some stub files that do the job, except for rotozoom, which does not appear to be in the GP2X libs, (and that I stole somewhere else). Clumsy, but it works for me.

Do *not* use the included version of rotozoom. The original version lie somewhere on the net, this version has been tampered for fcalc's purpose only.

** Release 0.1 **

- works for GP2X F200 f/w 4.0.0 only
