[avr-gcc-list] Question about gcc preprocessing and port/pin assignments

[James Washer]

I'd like to be able to say something like

#define switch PB7
.
.
.
setpin(PB7)

and have the following code generated

PORTB |= 1<<7


What I'm hoping for is the ability to change the definition of "switch" at any 
time, and have everything work

For example

if I change switch to PD2, the preprocessor would (auto)magically arrange for 
the following code

PORTD |= 1<<2


Any ideas?
