- Typos in env example environment (MCS51_COMPILER) and mcs51.rules (IAR compile)
- mangleAppC.pl handles uint64 and double types (abort compilation)
- Added dummy includes to prevent inclution of system includes (math.h, unistd.h)
- Compiling using sdcc now results in hex target (executable to hex conversion)
