 In that case it's not the known missing-include bug.  The next thing I'd
 check is that the `legacy-support` includes are happening ''before'' the
 OS includes.  In the other order, the OS headers would shadow the `legacy-
 support` headers, rendering them inoperative.

 In the particular case of `math.h`, there might be an additional
 complication regarding headers supplied by the compiler.

 When all else fails, try `cc -E`.
