Hi,

I am building Qt5 in cygwin. There is link error happened after the configuration,

g++ -shared /cygdrive/c/Qt/5.02/qtbase/src/corelib/QtCore.dynlist .....(be omitted)
/usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../../i686-pc-cygwin/bin/ld:/cygdrive/c/Qt/5.02/qtbase/src/corelib/QtCore.dynlist: file format not recognized; treating as linker script
