[Speex-dev] GCC/ELF Visibility patch (fwd)

Hi,
I've attached a patch against SVN r14645 which adds GCC visibility information
to all symbols exported from libspeex.so and libspeexdsp.so. It includes a
configure.ac change to test that both the compiler flags and
__attribute__((visibility)) works, and if so will
#define EXPORT __attribute__((visibility("default")))
and if not
#define EXPORT
I've attached a diff output of "nm -C -D" for both libraries (compiled on
x86_64 Linux), and verified that none of the symbols removed are mentioned in
any header file under include/
If this gets accepted, I'll make a similar effort for Win32 (where it hopefully
should suffice to #define EXPORT in the config.h)
