16

17
 * Machine-independent I/O routines for 8-, 16-, 24-, and 32-bit integers.
18
 *
19
 * Motorola processors (Macintosh, Sun, Sparc, MIPS, etc)
20
 * pack bytes from high to low (they are big-endian).
21
 * Use the HighLow routines to match the native format
22
 * of these machines.
23
 *
24
 * Intel-like machines (PCs, Sequent)
25
 * pack bytes from low to high (the are little-endian).
26
 * Use the LowHigh routines to match the native format
27
 * of these machines.
28
 *
29
 * These routines have been tested on the following machines:
30
 *	Apple Macintosh, MPW 3.1 C compiler
31
 *	Apple Macintosh, THINK C compiler
32
 *	Silicon Graphics IRIS, MIPS compiler
33
 *	Cray X/MP and Y/MP
34
 *	Digital Equipment VAX
35
 *
36
 *
37
 * Implemented by Malcolm Slaney and Ken Turkowski.
38
 *
39
 * Malcolm Slaney contributions during 1988-1990 include big- and little-
40
 * endian file I/O, conversion to and from Motorola's extended 80-bit
41
 * floating-point format, and conversions to and from IEEE single-
42
 * precision floating-point format.
43
 *
44
 * In 1991, Ken Turkowski implemented the conversions to and from
45
 * IEEE double-precision format, added more precision to the extended
46
 * conversions, and accommodated conversions involving +/- infinity,
47
 * NaN's, and denormalized numbers.

 * Removed ieeefloat.*

55
 * Revision 1.1  2000/09/28 16:36:53  takehiro
56
 * moved frontend staffs into frontend/
57
 * Need to debug vorbis/mpglib/analyzer/bitrate histgram.
58
 * still long way to go...
59
 *
60
 * HAVEGTK is changed ANALYSIS(library side) and HAVEGTK(frontend side)
61
 *
62
 * BRHIST is deleted from library. all the bitrate histogram works are
63
 * now in frontend(but not works properly, yet).
64
 *
65
 * timestatus things are also moved to frontend.
66
 *
67
 * parse.c is now out of library.
68
 *
69
 * Revision 1.2  2000/09/17 04:19:09  cisc
70
 * conformed all this-is-included-defines to match 'project_file_name' style
71
 *
72
 * Revision 1.1.1.1  1999/11/24 08:43:37  markt
73
 * initial checkin of LAME
74
 * Starting with LAME 3.57beta with some modifications
