ifnames - Extract CPP conditionals from a set of files
ifnames [OPTION]... [FILE]...
Scan all of the C source FILES (or the standard input, if none are given) and write to the standard output a sorted list of all the identifiers that appear in those files in '#if', '#elif', '#ifdef', or '#ifndef' directives. Print each identifier on a line, followed by a space-separated list of the files in which that identifier occurs.
