If you are using Lattice C :
Use the -b0 (thats a zero) switch when compiling your program. The default
in 4.0 (which was changed from 3.x) was to use 16 bit offsets for data
addressing and that won't work for arrays > 65533 bytes in size. Whereas
with -b0 you can address arrays up to two gigabytes. Be careful though
of preallocated arrays that are huge because it makes loading the code
at run time difficult if the memory space is fragmented. Often it is
better to use malloc() or calloc() to allocate those arrays. With MANX
I believe the latter is your only option at this time.

These opinions are my own and no one elses, but you knew that didn't you.
