configure reconizes this is the intent when the 44 <B>VERSION</B>, <B>tiff.alpha</B>, and <B>tif_version.c</B> 45 files are in the local directory (i.e. ``.'') 46<LI>configure no longer tries to setup HTML materials 47<LI>include file directories needed in building the library are now 48 specified with a <TT>DIRS_LIBINC</TT> config parameter 49<LI>configure no longer checks for alternate compilers if <TT>CC</TT> 50 is set; if the specified compiler is not found or is not appropriate 51 the configuration procedure aborts 52<LI>the <B>port.h</B> file generated by configure is now used only by 53 the library and as such as have been moved to the <B>libtiff</B> 54 directory 55<LI>there is beginning support for building DSO's on systems other than IRIX 56<LI>configure now verifies the JPEG and zlib directory pathnames by 57 checking for well-known include files in these directories 58<LI>configure no longer creates the <B>dist</B> directory needed only 59 on SGI machines (for building SGI binary distributions) 60<LI>a bug was fixed whereby configure would incorrectly set 61 <TT>ENVOPTS</TT> when building the software with gcc under AIX 62</UL> 63 64<P><HR WIDTH=65% ALIGN=right> 65 66<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> 67 68<UL> 69<LI>two new typedefs were added to <B>tiff.h</TT>: <TT>int8</TT> 70 and <TT>uint8</TT> for signed and unsigned 8-bit quantities, 71 respectively;

this was done for portability to non-UNIX systems 88<LI>support was added for the Acorn RISC OS (from Peter Greenham) 89<LI>the builtin codec table is now made <TT>const</TT> when compiling 90 under VMS so that <B>libtiff</B> can be built as a shared library 91<LI>support for the PowerPC Mac (from Ruedi Boesch) 92<LI>support for Window NT/Window 95 (from Scott Wagner) 93</UL> 94 95<P><HR WIDTH=65% ALIGN=right> 96 97<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A> 98 99<UL> 100<LI>the tools no longer include <B>port.h</B> 101<LI>various portability fixes;
