No, the problem is a "bit" more complicated: other LLVM files include
headers *other than* <signal.h>, and those headers in turn include
<signal.h>.  Grepping shows that <signal.h> is included only from the
following files:

./lib/System/Unix/Program.inc
./lib/System/Unix/Alarm.inc
./lib/System/Unix/Signals.inc

I tried to add #undefs in those files, but that did not fix the problem.
