unhappily it don't eliminated my problem :-(

Placing these externs give errors like this:
pro_man.c:74: extern definition for 'FSR2H' mismatches with declaration.
pic18f2680.h:5902: previously defined here

I tested just copy these definitions from pic18f2680.h:
extern __sfr __at (0xFF2) INTCON;
extern __sfr __at (0xFE0) BSR;
extern __sfr __at (0xFDA) FSR2H;
...

But still getting the old error:
pro_man.asm:1185: error: Symbol not previously defined (INTCON).

Please, some other suggestion?

Hmm, very interesting. But I need an OSEK compatible RTOS. I contacted
PICos18 author, but he don't have time to help me "port" it to SDCC.
He said me PICos18 uses many MPLAB C18 features and it will not works
easily on SDCC.
But I don't have choice, I don't have Windows and don't like it.
