0bca8f75bb Make ./config GCC 5.x aware
This patch makes two little things:
1. makes ../config GCC 5.x friendly
2. completely removes wavpack related stuff from Makefile if ../config --disable-wavpack given
Last one is for #35 issue. I also stuck into this when compiling w/o wavpack.
Compiled with this patch by gcc 5.1.0 on ArchLinux x86_64 from git master:
cd pcompress-master
patch -Np1 < ../gcc5.patch
./config --prefix=/usr --no-1.3-archive-compat --disable-wavpack
make
make install
have no problems and works fine.
