configure reconizes this is the intent when the 43 <B>VERSION</B>, <B>tiff.alpha</B>, and <B>tif_version.c</B> 44 files are in the local directory (i.e. ``.'') 45<LI>configure no longer tries to setup HTML materials 46<LI>include file directories needed in building the library are now 47 specified with a <TT>DIRS_LIBINC</TT> config parameter 48<LI>configure no longer checks for alternate compilers if <TT>CC</TT> 49 is set; if the specified compiler is not found or is not appropriate 50 the configuration procedure aborts 51<LI>the <B>port.h</B> file generated by configure is now used only by 52 the library and as such as have been moved to the <B>libtiff</B> 53 directory 54<LI>there is beginning support for building DSO's on systems other than IRIX 55<LI>configure now verifies the JPEG and zlib directory pathnames by 56 checking for well-known include files in these directories 57<LI>configure no longer creates the <B>dist</B> directory needed only 58 on SGI machines (for building SGI binary distributions) 59<LI>a bug was fixed whereby configure would incorrectly set 60 <TT>ENVOPTS</TT> when building the software with gcc under AIX 61</UL> 62 63<P><HR WIDTH=65% ALIGN=right> 64 65<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> 66 67<UL> 68<LI>two new typedefs were added to <B>tiff.h</TT>: <TT>int8</TT> 69 and <TT>uint8</TT> for signed and unsigned 8-bit quantities, 70 respectively;
