Feedback from usage while developing new features;
- Mis-matched integer sign comparison doesn't cause a warning
- And -Werror isn't set by default
Adding these as per below fixes things... but for cleanliness "unwanted
warnings" should probably be renamed, we want more warnings! :D
# disable any unwanted warnings
unwanted_warnings = [
'-Werror',
'-Wno-address-of-packed-member',
'-Wno-format-truncation',
'-Wsign-compare',
]
The performance of Ninja is amazing for testing shared-object builds and
version.map changes - feedback is instant. Makes light work of re-checking
ABI/API stuff.
