Turns out that more recent snapshots of gcc-4.7 emit even more of these,
so the fixes which I've done before tagging the 0.10.1 release are not
enough to build warning free with the latest gcc-4.7 snapshot <sigh>.
This fixes this.

When using config.h, it must be the very first include in all source
files since it contains #define that may change the compilation process
(eg libc structure layout changes when it's used to enable large file
support on 32 bit x86 archs). This commit adds it at the beginning
of all .c and .cpp files
We use get_opt_long, which allows non ambiguous abbreviations, but
since we didn't like that we have code that checks for abbreviations and
issues an error. But that code only handled separate argument and key like:
--bla value
and didn't handle them in the same arguemnts, like:
--bla=value
This patch fixes that, and gives a slightly better error report (it still
contains the =value part though)
