When GCC is invoked with -std=c99, the following errors are displayed when
including <spawn.h>:
/usr/include/spawn.h:69: error: static or type qualifiers in abstract declarator
/usr/include/spawn.h:69: error: static or type qualifiers in abstract declarator
/usr/include/spawn.h:72: error: static or type qualifiers in abstract declarator
/usr/include/spawn.h:72: error: static or type qualifiers in abstract declarator
We'd better remove the __restrict keywords here. The same is also done
in <regex.h>.
