[asterisk-dev] Update: Cross-compiling woes under openWRT

[Brian Capouch]

Bad news.  I just fetched trunk r81419 and not only are all the problems 
I mentioned in the email last week on this topic still there; there's 
another new one, and this time I can't overcome it to get things to build.

The build system still kicks out the COPTS warning as it processes each 
.c file.

I still have to add the function ast_atomic_fetchadd_int_slow() to both 
extconf.c and check_expr.c to get the compiler to proceed.

After kludging up the above fixes, the build now stops here:

I wish I could fix this stuff up on my own, but I can't.  I hope 
reporting it is of some use anyways.

Thanks.
