    This code still needs testing but is likely to be a huge improvemnt
    of support for Win32. Thanks Ross.

2003-10-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/dwvw.c
    Removed filedes field from the DWVW_PRIVATE struct.

    * src/file_io.c
    Change psf_fopen() so it returns psf->error instead of the file descriptor.
    Add new functions psf_set_stdio() and psf_set_file().

    * src/sndfile.c
    Change these to work with changed psf_fopen() return value.
    Remove all uses of psf->filedes from sndfile, making it easier to slot native
    Win32 API file handling functions.

    * src/test_file_io.c
    Minor changes to make it compile with new file_io.c stuff.

2003-10-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/gsm610.h
    Rename a variable from true to true_flag. As Ross Bencina points out,
    true is defined in the C99 header <stdbool.h>.

    * src/file_io.c
    If fstat() fails, return SF_TRUE instead of -1 (Ross Bencina).

2003-10-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/common.h
    Increase the size of SF_BUFFER_LEN and SF_HEADER_LEN.

    * src/sndfile.c
    Fix sf_read/write_raw which were dividing by psf->bytwidth and
    psf->blockwidth which can both be zero.

    * examples/sndfile-info.c
    Increase size of BUFFER_LEN.

2003-09-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * configure.ac
    Add checks for <sys/wait.h> and ssize_t.
    Other Win32/MinGW checks.

    * src/aiff.c src/au_g72x.c src/file_io.c src/gsm610.c src/interleave.c
      src/paf.c src/sds.c src/svx.c src/voc.c src/w64.c src/wav.c src/xi.c
    Fix compiler warnings.

2003-09-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * tests/scale_clip_test.tpl
    Add definition of M_PI if needed.

2003-09-19  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * configure.ac
    Detect if S_IRGRP is declared in <unistd.h>.

    * src/file_io.c tests/*.tpl tests/*.c
    More fixes for Win32/MSVC++ and MinGW. MinGW does have <unistd.h> but that
    file doesn't declare S_IRGRP.

2003-10-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/config.h.in
    Add comment stating that the sf_count_t typedef is determined when
    libsndfile is being compiled.

    * tests/utils.tpl
    Modified so that utils.c gets one copy of the GPL and not two.


2003-09-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * Win32/unistd.h src/sf_unistd.h
    Move first file to the second. This will help for Win32/MSVC++ and MinGW.

    * Win32/Makefile.am src/Makefile.am
    Changed in line with above.

    * Win32/Makefile.msvc
    Removed "/I Win32" which is no longer required.

    * src/file_io.c src/test_file_io.c tests/*.tpl tests/*.c
    If HAVE_UNISTD_H include <unistd.h> else include <sf_unistd.h>. This should
    work for Win32, MinGW and other fakes Unix-like OSes.

    * src/*.c
    Removed #include <unistd.h> from files which didn't need it.

2003-09-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * libsndfile.spec.in
    Apply fix from Andrew Schultz.

2003-08-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/test_log_printf.c
    Add tests for %u conversions.

    would over-write part of the header. Thanks to Axel Roebel for pointing
    this out. Axel also provided a patch to fix this but I came up with a
    neater and more general solution.
    Return error when openning an AIFF file with data after the SSND chunk
    (Thanks Axel Roebel).
