all mingw installation i tried had only static libraries inside /usr/lib

you may possibly get the gdal internal copy of libz using 
"--with-libz=internal", but you need to find a way to get a shared copy of 
libm. you should probably ask to the mingw list.

this is true only inside the source tree. after 'make install' you can use 
normal link commands, no libtool required.

there should be no problem (after installing gdal)
