<I>previous</I> and <I>current</I> versions (see above).

If you don't find something listed here, then it was not done in this

<LI><B>configure</B> now captures significantly more information
|
|
|
41 |
in the <B>config.log</B> file and provides more information when
|
|
|
42 |
it is unable to setup a configuration
|
|
|
43 |
<LI>support was added for building shared libraries on more systems:
|
|
|
44 |
AIX, HPUX, Solaris, and Linux.
|
|
|
45 |
<LI>a new configuration parameter <TT>LIBCOPTS</TT> was added for
|
|
|
46 |
passing arguments to the C compiler to use when building only
|
|
|
47 |
the library; this is part of the enhanced support for building
|
|
|
48 |
shared libraries
|
|
|
49 |
<LI>include files for optional packages that reside in <B>/usr/include</B>
|
|
|
50 |
are now handled correctly
|
|
|
51 |
<LI>build trees may now be configured using either relative or absolute
|
|
|
52 |
pathnames to the source distribution
|
|
|
53 |
<LI>several new configuration parameters were added, mainly for building
|
|
|
54 |
shared libraries: <TT>DIST_MAJOR</TT>, <TT>DIST_MINOR</TT>,
|
|
|
55 |
<TT>DIST_ALPHA</TT>, and <TT>DSOSUF_VERSION</TT>

63 |
<LI>the Deflate support has been revised: it requires version 0.99 of
|
|
|
64 |
the zlib software distribution, <B>the output format has changed and
|
|
|
65 |
is incompatible with previous versions of this library</B> (each
|
|
|
66 |
strip now includes a header read and written by the zlib library)
|
|
|
67 |
<LI>the codec name printed by the TIFFPrintDirectory routine is now
|
|
|
68 |
taken from the codec table instead of from a builtin table; this means
|
|
|
69 |
that application-defined codecs are handled correctly
|
|
|
70 |
<LI>a new symbol was added that contains the library version number;
|
|
|
71 |
this can be used to do a compile-time compatibility check of the
|
|
|
72 |
library version
