What I said before about check_header applies here too.
Seeing this rather repetitive code, I'm thinking perhaps we should add a
new helper function:
check_code(){
headers=$1
code=$2
shift 2
{
for hdr in $headers; do
echo "#include <$hdr>"
done
echo "int main(void) { $code; return 0; }"
} | check_ld "$@" && enable $funcs && enable_safe $headers
}
Then use it like this:
check_code intrin.h "int info[4]; _cpuid(info, 0)" && enable cpuid
