my solution:

[tommy@alfread scheduler]$ diff process.c process.c.fix
541a542

#ifdef HAVE_POSIX_SPAWN
545c546

<

#endif
547a549,550

#ifdef HAVE_POSIX_SPAWN
555c558,561

<

#else
real_argv[2] = profile ? profile : "none";
real_argv[3] = (char *)command;
#endif

Current CUPS requires POSIX conformance for Unix operating systems. What OS and compiler are you using?

I'm using arm-linux-gcc cross compile for arm.
Seems it will cause compile issue if HAVE_POSIX_SPAWN not define.
So I try to handle it while POSIX not supported.
Just make it more tolerant.

Fixed in Subversion repository.

Your proposed fix was incorrect and would cause filters to run as root... The correct "fix" is attached, although longer term we will no longer support non-POSIX systems.
