But your fix is also incomplete.  For example:

this issues the warning for posix_spawnattr_getflags, but calls 
posix_spawnattr_getsigdefault.  I'll commit a followup if you don't beat me to 
it.

I'm sorry about all this.  I was obviously too hasty this morning, and ended up 
pushing several flawed patches.
