I'm sorry, I don't want to use "sed -i".  That loses the original file
and makes it harder to reconstruct what has happened.

I don't understand that.  <sys/wait.h> is a system header file.  Are
you saying that it is impossible to use <sys/wait.h> and WIFCONTINUED
unless your source code does a #define WCONTINUED before #include'ing
<sys/wait.h>?  That seems like a bug in the Hurd library code.

I get that "comm" doesn't work, but the change in that patch is simply
incorrect.  If you don't pass "comm", the "grep sleep" will never
succeed.  If there is no way to support this code on Hurd then we
should skip it, not put in a command that can never work.
