|
|
// one attempted to access build configuration variable without including the

// header by simply using -Wundef compiler attribute.

|
|
// NOTE: Not having things explicitly defined to 0 is harmless (in terms it
|

// follows same rules as Google projects) and will simply cause compiler to

// become more noisy, which is simple to correct.
