BUILD: Makefile: shut certain gcc/clang stupid warnings
The recent gcc and clang are utterly broken and apparently written by
people who don't use them anymore, because they emit warnings that are
impossible to disable in the code, which is the opposite of what a
warning should do. It is however possible to disable these warnings on
the command line.
This patch adds when supported :
-Wno-format-truncation: bogus warning which is triggered on each
snprintf() call based on the input type instead of the variables
ranges, resulting in the impossibility to use "%02d" and similar.
-Wno-address-of-packed-member: emitted for each and every line in
ebtree.h by recent clang. Probably that the warning's author has
never understood the use cases of packed structs and should be
taught the use cases of the language he writes the compiler for.
-Wno-null-dereference: emitted by clang on *(int *)0 = 0. The code
will be updated to use a volatile instead but this recent change
of behaviour will certainly cause quite some bugs in decades of
existing code.
Feel free to report new such stupid warnings and to propose patches
to complete this list.
