2Wrapping the tiff support library for tcl is a bit more complicated
3than libz, or libpng.
4
5(1) libtiff comes with its own configure command, and there is no
6 configure.ac. This means that it is not possible to lift the
7 relevant sections out of it for the configure of the
8 binding.
9
10 Also this configure is not exactly autoconf based (Seems so).
11 One of the things it has to be told is the target/build architecture,
12 as argument instead of via option. Because of this we cannot use
13 AC_CONFIG_SUBDIRS to run the sub-configure.
14
15 We do it directly, and are thus also able to avoid the symlink
16 we had to have in libjpeg/tcl.
17
18(2) The tif sources have usage of tdarg.h hardwired into them.
19 This means that a compiler not using this header, but varargs.h
20 cannot be used. This is checked in configure.
