Hi,
A regression seems to have slipped in the latest trunk (between 20120705
and 20120709). One of the testcases which we're using to test the Fedora
mingw-w64 toolchain now fails to build with the latest trunk. It is a
testcase which tests static linking to the Qt library for the win32
target:
$ cat qt_test_static.pro
TARGET = qt_test_static
TEMPLATE = app
SOURCES += main.cpp
CONFIG += static
$ cat main.cpp
#include <QCoreApplication>
int main(int argc, char *argv[])
{
QCoreApplication(argc, argv);
return 0;
}
$ mingw32-qmake-qt4 qt_test_static.pro
$ make
make -f Makefile.Release

This specific testcase works fine for shared libraries (win32+win64) and
for static libraries for the win64 target.
I suspect commit
http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64?view=revision&revision=5169
to be the culprit.
Is this really a regression or do you think it would be sufficient to
rebuild the Qt library?
