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
