* Furthermore, use NDEBUG globally to detect the presence
of building with more debug output information.
AX_CHECK_ENABLE_DEBUG is easier to use, and nowadays
Gnome has also switched to it from its own custom solution.

These fixes are in the public API, but FLAC would have been extremely
unlikely to work in any system where `unsigned` was not 32 bits.
Therefore we do not treat this as an API change.
Previously, it the write callback failed the error status
would be set to `FLAC__STREAM_DECODER_READ_FRAME`. Now it
gets set to `FLAC__STREAM_DECODER_WRITE_STATUS_ABORT`.

Adds two new apodization functions that seem to perform better than
the apodization functions currently in the codebase and fixes three
existing windows as well.
Its important to note that this patch only affects the encoder stage
that evaluates various possible predictors. Audio encoded with these
new windows will still decode with existing legacy decoders.
= Theory =
These functions are used to window the audio data at the predictor
stage. These news functions enable the use of only part of the signal
to generate a predictor. This helps because short transients can
introduce noise into the predictor. The predictor becomes very good
at prediciting one part of the signal, instead of mediocre for the
whole block.

* Replace _declspec with __declspec.
* Replace __wgetmainargs_ with __wgetmainargs_t and __wgetmainargs
with wgetmainargs because identifiers with leading underscores are
reserved for the compiler.

These were most arising from -Wenum-conversion where an enum of
one type was being assigned to a variable on another.
Originally reported by Lenny Maiorani <lenny@colorado.edu> on the
flac-dev mailing list.
With gcc >= 4 and ELF, set default visibility to hidden and make visible
only the symbols with FLAC_API or FLACPP_API.
A convenience libFLAC-static.la is created for test_libFLAC as it
depends on the hidden symbols.
This change assumes that a C99 <stdint.h> header is available. For
compilers where that is not the case, the user should provide a
minimal replacement header.
