The attached patch fixes the following issues:
Check pointers returned by malloc. It may return NULL on allocation failure.
Replace random size check. 40Mb is just random and it can easily be hit in the real world.
Use 4G instead, which is a better limit (32-bit address space limit).
If the machine does not have enough memory, malloc will tell us. There's no need to
check against...

The attached patch fixes a rendering bug that results in the attached shapes-broken.pgm image. The expected image is attached as shapes.pgm.
The patch replaces a comparison ((float)x == 0.0) by (fabs(x) < very_small_fp_value).
Due to floating point not being exact, it depends on the FP format and the CPU whether a direct comparison will be true or not.
The ==0.0 test breaks on PowerPC and...

This also fixes compilation for x86_64.

The attached patch fixes more fgetc()s, which put their result into a char. The result must be put into an int, because otherwise it breaks wrt EOF on systems with char=unsigned char.

On systems like PPC and Sparc a C "char" is unsigned by default.
So it can not hold the magic EOF that's returned by fgetc() on end-of-file, because EOF usually is -1. So the parser fails to detect and end-of-file condition on such systems.
The attached patch fixes this by using "int" for the "ch" variable. (fgetc() also returns an "int" type)

The following patch fixes a linker error on PPC due to the compiler choosing to not inline the sub_cross2d function.
