I know several. In fact no C compiler understands __LINE__. 
The standard preprocessor cpp does however understand __LINE__.
It is perfectly possible to use cpp on Ada source as well, but
I wouldn't recommend it.
Decent version control systems usually supply a way to get the
integer literal of the current line number inserted in the source.
