-dnl Most systems put the real signal names in /usr/include/sys/signal.h.
-dnl Linux puts them in /usr/include/asm/signal.h. CygWin32 puts them
-dnl somewhere else altogether. This hack attempts to parse the output
-dnl of saying `#include <signal.h>' to the preprocessor in order to find
-dnl the full path of files named signal.h. The first sed substitution
-dnl handles paths on CygWin32, and is a good example of why rc's quoting
-dnl rules are superior to sh's. If this process doesn't produce any
-dnl filenames, fall back to the (Unixoid) defaults.
