Hello I've just successfully lit a LED with a atmega88 using GDC.
(AVR is a 8bit micro controller with 16bits pointers)
I had to change GDC to accept a zero critsize and implemented
these stubs for volatile operations on the memmory mapped IO.
extern (C) void _d_criticalenter() {}
extern (C) void _d_criticalexit() {}
The toolchain is using newlib for now.
My next step is to try making it with the avr-libc, and then get the
IRQs working with the prologue and epilogue generated by it.
Regards, Marcelo
Another +1. Would be awesome to see this as a git repo and/or some
howto. After all I used to teach folks basics on MCUs with precisely
these chips (and then there are *duinos sold everywhere).
