log
@libmatheval: update to 1.1.12.

Version 1.1.12

* Updated build system to work with current GNU autotools.  Guile is
  needed for test suite only, which now works with Guile 2.0 and later.
* Fixed buffer overflows in the Fortran interface and in handling of
  very long strings (reported by Hongduo Zhao).
* Fixed memory leaks on parsing error, and in Flex generated scanner.
* Characters not part of the notation are now reported as error,
  instead of being echoed to standard output.
* Fixed wrong simplification of 0^x.
* Fixed wrong derivatives of asinh() and acoth() functions.
* Inverse hyperbolic functions are calculated by C library, fixing
  inaccurate results for very small or very large arguments.
* Added min(), max() and select() functions.  Note that min, max and
  select therefore can not be used as variable names any more.
* Library exports its interface only, so that its internal symbols
  (including these of Lex and Yacc generated code) do not clash with
  symbols of program any more.
* Fixed compiler warnings and undefined behavior.
* Fixed errors in the manual, and added short example at its beginning.

To avoid xmalloc from the test suite polluting the name space.
