Soren Jorvang 30e437f9e3 Fix some cases of variables being used uninitialized. Also some unused 
variables, writeable strings and dangerously shadowed variables.

index(), gamma(), exp() and y0() are POSIX functions and using those
names can cause namespace confusion.

A number of C files were missing the final newline required by ANSI C
and some versions of GCC are pedantic enough to complain about this.

These changes simply the scons build, allowing us to get rid of
filterWarnings which is simply more trouble than it's worth.
