Description of problem:


From the NEWS file:


+Version 1.4.10 - 09 Jul 2007, by Eric Blake  (CVS version 1.4.9c)
+
+* Upgrade from GPL version 2 to GPL version 3 or later.
+* A number of portability improvements inherited from gnulib.
+* Avoid undefined behavior introduced in 1.4.9b in the `format' builtin
+  when handling %c.  However, this area of code has never been documented,
+  and currently does not match the POSIX behavior of printf(1), so it may
+  have further changes in the next version.
+
+Version 1.4.9b - 29 May 2007, by Eric Blake  (CVS version 1.4.9a)
+
+* Fix regression introduced in 1.4.9 in the `eval' builtin when performing
+  division.
+* Fix regression introduced in 1.4.8 in the `-F' option that made it
+  impossible to freeze more than 512 kibibytes of diverted text.
+* The synclines option `-s' no longer generates sync lines in the middle of
+  multiline comments or quoted strings.
+* Work around a number of corner-case POSIX compliance bugs in various
+  broken stdio libraries.  In particular, the `syscmd' builtin behaves
+  more predictably when stdin is seekable.
+* The `format' builtin now understands formats such as %a, %A, and %'hhd,
+  and works around a number of platform printf bugs.  Furthermore, the
+  sequence format(%*.*d,-1,-1,1) no longer outputs random data.  However,
+  some non-compliant platforms such as mingw still have known bugs in
+  strtod that may cause testsuite failures.
+* The testsuite is improved to also run gnulib portability tests for the
+  features that M4 imports from gnulib.
