Description:
Analogically to Bug #26294 - library name conflict between MySQL 4.x, 5.0 and Qt 3.3, but this time in version 4.1.22 on windows. Since this bug was fixed only in 5+ versions of MySQL I include patch to solve it in 4.1.* release as well.
Tested on windows XP SP3.
How to repeat:
Link any program that uses both qt-mt.lib from Qt v3.3x (non-threaded versions
not tested) and mysqlclient.lib from v4.1.*
Suggested fix:
