Summary: Function parameters on pic 18f1220

Initial Comment:
I'm using a pic 18f1220 and i have to make some functions with parameters but they don't work..
For example:

void foo(unsigned char c) {
PORTB = c;
}
main() {
...
foo(133);
...
}

don't work, i think the parameter variable c contains 0, but:

main() {
...
PORTB = 133;
...
}

works well..

Same problem with sdcc v 2.6 and sdcc 2.8.
I'm compiling with:
/usr/bin/sdcc/sdcc -mpic16 -p18f1220 -V --debug -Wl-omain.hex -Wl-m -Wl-ainhx32 main.c

Please try the svn version.

I had similar issues with a pic18f2685, where function arguments, local
variables and vectors didn't work. I suspected the crt code was the
problem, and forcing the use of crt0.o seemed to solve it.

With the latest svn code the crt issues seem to be solved, so you could
give it a try..
