Compiling problem

[lemio]

When I try to compile this files using flash.py:

In file included from stepper.c:45:0:
/usr/lib/gcc/avr/4.5.3/../../../avr/include/util/delay.h: In function ‘homing_cycle.clone.0’:
/usr/lib/gcc/avr/4.5.3/../../../avr/include/util/delay.h:230:28: error: __builtin_avr_delay_cycles expects an integer constant.

Looks like the avr-libc people have made some non-backward compatible changes. Fix is in latest commit. Let me know if it works for you.

Still the same issue:
geert@geert-R509:~/Downloads/stefanix-LasaurGrbl-f4b2c1b (2)$ sudo python flash.py /dev/ttyACM0
Using serial device '/dev/ttyACM0' from command line.

I just double-checked and I cannot reproduce the compile error. I tested on Ubuntu64 12.04 and Windows 7 both with the Arduino 1.0 tool chain.

Can you give me more info to reproduce the error? What is your build environment?
