hi all!
I have to build mysql++ a second time (firstly with msvc which was flawless) for compatibility issues.
the libraries were compiled successfully, both debug and release, but i encounter an error
while linking against mysql lib:

cd lib && mingw32-make BIN_DIR=release

hi! i discovered that "libmysqlclient.def" misses 2 symbol names:

mysql_more_results@4
mysql_next_result@4

having added these, the examples compiled. i now only have problems
concerning simple2.exe and simple3.exe.
you are using german umlauts in "Nürnberger Brats". in simple2.exe these
umlauts are displayed correctly, but in
simple3.exe, where it uses the 'use-query', i get funny symbols instead
of a 'ü'. i use latin1 for my mysql database,
if that's helpful...
