It should be parsed but ignored by the compiler. The fact that this doesn't work in your case is a problem with the compiler. I will have a look at it. The xdata keyword is not standard C. It is used by 8051 compilers to specify a memory segment where the data is located. > The keyword reentrant is also being used but I think from my research that > it is okay to leave it out if I make sure the function only uses registers > or stack variables? The reentrant keyword is non standard, too. Since the 8051 has a very small stack (even smaller than the hardware stack of the 6502), the C compiler will place variables in static storage unless told otherwise by this keyword. It is somewhat similar to the --static-locals compiler option of the cc65 compiler (or the equivalent #pragma). The difference is that when using cc65, all variables are on the stack by default.
