The current kernel with a configuration similar to the default configuration for the 0.1.3 version, compiled with BCC has a code size of 51216 bytes. With the new compiler, size is 48288 bytes.

Actually, code size <= 64KB and separately (data + bss + stack sizes) <= 64KB. > Do you think/know if GCC may solve this limit, being able to produce > multi-page binaries? No, those limits still holds.
