fparser-4.5.2-bp156.3.4

- Update to 4.5.2
  * Fixed several optimizer bugs.
  * Fixed compilation problems with Visual Studio 2013 and gcc.
- Use url for source

- Mark package as requiring mpfr >= 2.4.0 due to use of mpfr_d_sub

- Update to new upstream release 4.5.1
  * Reverted the automatic C++11 detection to a precompiler macro
  setting (FP_SUPPORT_CPLUSPLUS11_MATH_FUNCS) because not all
  compilers yet fully support the C++11 math functions.
  * Fixed a potential duplicate symbol problem that happens with
  explicit template instantiations.

- Update to new upstream release 4.5.0
  * Removed support for the "eval()" function from the supported
  syntax. (This function was too dangerous, too difficult to maintain
  internally, not very useful, and more or less a gimmick in the
  first place.)
  * Removed several of the conditional compiling macro definitions,
  namely FP_SUPPORT_TR1_MATH, FP_ENABLE_EVAL, FP_EVAL_MAX_REC_LEVEL,
  FP_NO_EVALUATION_CHECKS and FP_EPSILON.
  * The epsilon value used in comparisons is now set with a member
  function of FunctionParser (which allows setting different values
  for different versions of the parser).
  * The math functions previously turned on with FP_SUPPORT_TR1_MATH
  are now automatically used if __cplusplus indicates that C++11 is
  in use.

- enabled -DFP_SUPPORT_TR1_MATH_FUNCS -DFP_SUPPORT_COMPLEX_NUMBERS
- patch to compile with gcc4.7 (gcc4.7.patch)

- Initial package for build.opensuse.org
