- Update to 2.16.01:
* Fix the creation of the table of contents in the HTML version
of the documentation.

- Update to 2.16:
* Support for the rdf format has been discontinued and all the
RDOFF utilities has been removed.
* The --reproducible option now leaves the filename field in the
COFF object format blank. This was always rather useless since it is
only 18 characters long; as such debug formats have to carry their own
filename information anyway.
* Fix handling of MASM-syntax reserved memory (e.g. dw ?) when
used in structure definitions.
* The preprocessor now supports functions, which can be less verbose
and more convenient than the equivalent code implemented using
directives. See ppfunc.
* Fix the handling of %00 in the preprocessor.
* Fix incorrect handling of path names affecting error messages,
dependency generation, and debug format output.
* Support for the RDOFF output format and the RDOFF tools have been
removed. The RDOFF tools had already been broken since at least NASM
2.14. For flat code the ELF output format recommended; for segmented
code the obj (OMF) output format.
* New facility: preprocessor functions. Preprocessor functions, which
are expanded similarly to single-line macros, can greatly simplify
code that in the past would have required a lengthy list of directives
and intermediate macros. See ppfunc.
* Single-line macros can now declare parameters (using a &&
prefix) that creates a quoted string, but does not requote an
already quoted string. See define.
