xspec patches

A few new patches have been added recently. 12.4.0x fixes a number of problems that showed up when using the new g++-4.3.0 compiler and when using gcc on Solaris platforms. This patch level is released as part of HEAsoft 6.4.1. 12.4.0y improves the handling of cases when the L-M algorithm pegs a parameter due to a zero or negative pivot value in the Hessian. 12.4.0z keeps the fit valid when the fit method is changed. This allows the improve command to be run after an L-M fit. 12.4.0aa is a fix to allow filenames prompted for by the fakeit command to being with a / ie to be absolute paths. Patches available from the usual place.
