Now compiles everything whether we need it or not, removing whole files with #ifdefs...this will make it easier to "embed" this library in other projects or use a different build system: just push everything through the compiler with preprocessor defines for the parts you want/need...platform modules are determined automatically without the build system needing to intervene, so you just have to #define the archivers, etc that you want.
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
