The following packages have been upgraded in the Cygwin distribution:

* m4	1.4.19

An implementation of the traditional Unix macro processor. It is mostly
SVR4 compatible although it has some extensions (for example, handling
more than 9 positional parameters to macros). GNU m4 also has built-in
functions for including files, running shell commands, doing arithmetic,
etc.

For more information see the project home pages:

	https://www.gnu.org/software/m4/
	https://sv.gnu.org/projects/m4/

For changes since the previous Cygwin release please see below or read
/usr/share/doc/m4/NEWS after installation; for complete details see:

	/usr/share/doc/m4/ChangeLog
	https://git.sv.gnu.org/gitweb/?p=m4.git;a=log;h=refs/tags/v1.4.19


Noteworthy changes in release 1.4.19 (2021-05-28) [stable]

* A number of portability improvements inherited from gnulib, including
   the ability to perform stack overflow detection on more platforms
   without linking to GNU libsigsegv.


Noteworthy changes in release 1.4.18d (2021-05-11) [beta]

* A number of portability improvements inherited from gnulib.


Noteworthy changes in release 1.4.18b (2021-05-07) [beta]

* The symbol hash table now defaults to 65537 buckets instead of 509, as
   modern systems have enough memory to benefit from fewer hash collisions
   by default.

* Introduce the use of gettext, with the immediate benefit of nicer
   UTF-8 author names.  Over time, more translations of program messages
   will become available.

* A number of portability improvements inherited from gnulib.
