Changes from v1:
Modifications to "t/ax/depcomp.sh" have been moved to a dedicated patch
-- 8< --
This is related to an effort to prepare Automake for future GCC/Clang
versions which set c99 as default standard to be used.
Function should be properly declared prior to use in order to be
compatible with c99 standard.
This is valid for both local functions and standard functions (as
printf).
