Bo Victor Thomsen replied offline and pointed me to the page 
http://www.adp-gmbh.ch/win/misc/mingw/dll.html and it seems (as Teemu 
reports to me) that the simple

\MinGW\bin\gcc.exe -shared $source_files -o libral.dll

works. I'm now even tempted to try to build my complete 
GDAL+Gtk2+libral+Perl modules -system on Windows.
