xerces-c, xerces-c-devel, xerces-c-doc 2.1.0-2 available for review/upload

[Abraham Backus]

I added a patch to follow some recommendations from Gerrit.   1) have the library name be "cygxerces-c2_1_0.dll" rather than "libxerces-c2_1_0.dll" (following conventions used by other libraries in cygwin).   2) the symlinks created in the build structure during "make" more accurately represent the links created during "make install"   3) in "make distclean" and "make clean", libraries and symlinks are removed   http://abackus.imagineis.com/xerces-c/setup.hint http://abackus.imagineis.com/xerces-c/xerces-c-2.1.0-2.tar.bz2 http://abackus.imagineis.com/xerces-c/xerces-c-2.1.0-2-src.tar.bz2   http://abackus.imagineis.com/xerces-c-devel/setup.hint http://abackus.imagineis.com/xerces-c-devel/xerces-c-devel-2.1.0-2.tar.bz2   http://abackus.imagineis.com/xerces-c-doc/setup.hint http://abackus.imagineis.com/xerces-c-doc/xerces-c-doc-2.1.0-2.tar.bz2   Anyone wishing to review these packages can point setup.exe to http://abackus.imagineis.com.   -Abe
