I suppose that the trick is in the "-" sign here. If this command fails for any reason you get warnings and errors but the build still continues with the current version of the .h/.c files, and we are left with telling users "no no, ignore this build error, everything is fine".
The same just-ignore-it behavior can bite if the script genuinely fails after you just made a typo in one of the input files, for example. Doesn't look particularly clean to me, if you want my opinion.
A bientot,
Armin
