The following is a file ioCC1110.h which is a header file copied from Texas Instruments for their CC1110 Radio/microprocessor chip which I am using to develop a signalling system for miniature railways. The processor is an 8051.
It all seems to be in order but when I assemble/compile it with Silicon Industries IDE as recommended, using Raisonance assembler,Ride7/bin/MA51 , I get the error “ C091 in line 220 of ioCC1110.h: invalid parameter declaration”. Does Raisonance apply the SBIT word in this context. I include the opening of ioCC1110.h which gives the SBIT macro define, and then line 220 to 230 which are the opening data statements for SBIT. SFR and SFRBIT seem to work OK.

#define SFR(name , addr)
#define SFRBIT(name, addr, bit7, bit6, bit5, bit4, bit3, bit2, bit1, bit0)
#define SBIT(sbit name,addr) // sbit name = addr;
#define VECT(num,addr) num
#ifdef __C51__
#define XREG(addr) ((unsigned char volatile xdata *) 0)[addr]
#elif defined __AX51__ || defined __A51__
#define XREG(addr) addr
#endif

Can anybody help a learner, C++ seems to have so many different dialects.
