When I try to build version 1.2.13 on Windows using Visual Studio (both 2005 and 2008) I get the following:
1>------ Build started: Project: libhunspell, Configuration: Release_dll Win32 ------
1>Compiling...
1>utf_info.cxx
1>..\hunspell\utf_info.cxx(4) : error C2552: 'utf_lst' : non-aggregates cannot be initialized with initializer list
1> 'unicode_info' : Types with user defined constructors are not aggregate
1>..
Moving the definition of the unicode_info struct from csutil.cxx back to csutil.hxx where it was previously fixed the problem.
Sorry about the duplicate - it happened unexpectedly when I refreshed my browser.
