Hi, I just recently downloaded your Boost C compiler. I'm new to PIC programming, though I am an advanced C++ programmer and have been coding for several years. One little anonyance I noticed with your compiler is the definition of integer binary constants. With your compiler a constant integer is defined as follows: 11111110b (corresponding to the decimal value 254) While I know that the ANSI standard does not define a method of declaring integer constants in binary (they expect you to do 0xFE in this case.) It would be nice if your compiler would accept the following notation: 0b11111110 As all of the other C compilers that support defining binary integer constants that I have used do it that way, it flows much more logically from the '0x' notation ANSI C uses. Thank you for your time.
