* use -Wall -Wno-unused -Wno-pointer-sign -Wno-uninitialized
-Wno-switch -Wno-strict-overflow -Wno-main
instead of -W when warnings are not enabled with GCC based compilers.
Using only -W only is rather useless because this switch enables
warnings which can be usually ignored in 3-rd party code.
This modification should help in locating bugs introduced by us
to 3-rd party code, i.e. due to wrong header files used on some
platforms (we do not use autoconf assuming some default settings
what can be wrong in some cases). It should also not hide some
important/critical bugs in 3-rd party code.
This modification pacifies some common warnings which can be
ignored usually but it also enables some more important ones.
If it's necessary then we can tune it a little bit more and disable
some other warnings too.
It's possible that on some platforms using very old GCC versions
some of -W* switches are not supported - please make tests and
inform us about problems.
