libxml2.i386 0:2.7.3-1.fc11 Line 422 of /usr/include/libxml2/libxml/xmlversion.h checks to see if ATTRIBUTE_PRINTF is not defined. If it is then it falls through to line 429, where it promptly proceeds to redefine it. This causes an issue when a wxGTK app is built since wxGTK defines its own ATTRIBUTE_PRINTF. One example of such an app is xmlcopyeditor 1.2.0.2, which I am trying to build for Rawhide.
Created attachment 332994 [details] Patch to remove excess ATTRIBUTE_PRINTF definitions I also found another definition after. This patch should fix this issue.
Fixed in a completely different way upstream, see http://mail.gnome.org/archives/xml/2009-April/msg00021.html thanks, Daniel
