However, note that we don't need to return a random number as the PID, we could get a bit fancier (look at the source of our getpid() for ideas ;-). > > > Why does gettext need these functions? > > > > Because it invokes subsidiary programs to do certain jobs. > > I guessed that. 8) But I meant is it vital to gettext's functionality?

If spawn* will do, we could simply make posix_spawn* call spawn*, and gain both an ease of porting and a useful new function. > FWIW glibc 2.1.3 on Linux does not seem to have posix_spawn*. I can't believe > gettext has shipped without being tested on any RedHat Linux 6.2 boxen. Believe it. Gettext developers are not bothered too much about old systems (isn't the latest version of RedHat 7.something?).
