Try this: $ <target>-gcc -c foo.c $ <target>-objdump --disassemble foo.o Or use the -S option to gcc, and look at the asm. One of the things you'll see is gcc inserting a call to something like __main() before it runs the first line of main().

Yea, but a minor one. You just have to run make one more time, with some flags. Trivial stuff, and very reliable. b.g. -- Bill Gatliff bgat@billgatliff.com ------ Want more information?
