[GiNaC-list] Release GiNaC 1.5.4

[Jens Vollinga]

Hi everybody,

GiNaC 1.5.4 is out and available. The changes are:

* Default parser now can again read in user defined classes.
* Add mul::info() and add::info() support for numeric info_flags
   (GiNaC now can detect that the sum or product of a number of
   positive expressions is again a positive expression).
* Fixed cast that caused compile error on 64bit machines.
* Fixed incorrect uses of STL iterators.
* Removed subdirectory debian.
* Output LaTeX-symbols using \mathrm, instead of \mbox.

As always, this release can be downloaded from

Best wishes,
Jens
