This was so far the worst case of -Werror=implicit-function-declaration
I encountered:
- a missing #include <stdlib.h> (for exit()) caused a configure test to fail
- that didn't cause the configure step to fail (or silently disable some
feature)
- but enabled a fallback codepath which had tons of errors triggering on
-Werror=implicit-function-declaration
;-)
Perhaps you could add to your wiki entry about this bug class that there
may be non-obvious problems during the configure step caused by
-Werror=implicit-function-declaration that might
- silently disable features (because detection failed)
- enable unwanted fallback codepaths for "missing" (becuase misdetected)
features
