I'm not sure that helps. (if it is just a global turn it off).
We would like :
- (a) not to get false assertions (when 'l1_text' is used)
- to get proper assertions when:
- (b) someone does a typo (when 'l1_test' is used)
- (c) compiled on a system which doesn't support this (like x86)
to make sure we didn't polute anything we should not have
Adding things to the source will cause c to fail.
using something like -Wno-attributes will cause b to fail (unless you were
thinking it would take a list on the command line)
-Wno-attributes foo,bar,l1_text
?
