I'm going to have a go at patching the compiler to get rid of
it either altogether,
I'm lazy, so I just disabled that warning completely. Here's
the patch agains gcc 3.2.whatever.
i've scanned the gcc sources and docs and found that
#pragma GCC system_header
sets the "in_system_header" variable seen in th ecode below.
however, that does not help directly in our case, as the "system header"
tag is not carried along with the function like macro.
it however switches the warning if you put it in the source file (or
include it within the _BIC_SR_IRQ macro using _Pragma("...")). but it
also disables all the warnings for the rest of the file, after the macro
is used :-(
i guess the patch isn't that bad. i'll probably include it for future
releases.
