Turn on -Werror=implicit-function-declaration
|
|
|
|
|
|
|
|
|
|
GCC 4.4, the minimum compiler version, supports this option. Unlike
|
|
|
|
|
other warnings, -Wimplicit-function-declaration warnings should be
|
|
|
|
|
independent of compiler versions, so this change should not cause
|
|
|
|
|
compiler-specific build failures.
