Various cleanups and auto-fu tweaks. * Make Makefile.am files look alike as much as possible. * Remove debug: target and don't mess with the users DEBUG environment variable: Autoconf checks for -g and automatically adds it to CFLAGS, which is overridden by the user's $DEBUG. If the user didn't specify one, "make install" will strip the resulting binaries and leave the debugging symbols intact otherwise. * Remove profile: target, as it is quite pointless in Ezstream. Also, the user can add profiling flags via the $DEBUG variable as well. * Remove -ffast-math and -fsigned-char from gcc, and enable two additional warnings instead. * Unconfuse Solaris compiler flags (unfortunately, the configure script still fails in the libshout check with some obscure linker error): Do not force -x04 and -fast optimizations, let the user decide (it doesn't matter for Ezstream anyways.) Remove -xgc92, which is deprecated and actually makes the resulting binary run slower on SPARC. Also remove -fsimple, which does not help and has the potential of causing trouble, and don't enable verbose warnings just to disable them afterwards with -w. Leave only -v for verbose warnings. * Const'ify getFormat*() functions and blankString, and squelch a few const- related warnings. * Squelch a signedness warning and fix two ;; syntax errors. * Add a snapshot target to Makefile.am that creates a tarball of the form ezstream-snapshot-YYYYMMDD.tar.gz. git-svn-id: https://svn.xiph.org/trunk/ezstream@12562 0101bb08-14d6-0310-b084-bc0e0c8e3800
