The complete syntax is:
gcc -shared -o cyg${module}.dll \
-Wl,--out-implib=lib${module}.dll.a \
-Wl,--export-all-symbols \
-Wl,--enable-auto-import \
-Wl,--whole-archive ${old_lib} \
-Wl,--no-whole-archive ${dependency_libs}
Where ${module} is the name of your DLL, ${old_lib} are all
objectfiles, bundled together in a static lib or single object
files and the ${dependency_libs} are importlibs you need to
link against, e.g '-lpng -lz -L/usr/local/special -lmyspeciallib'
All symbols are exported then because you tell the linker to do so:
-Wl,--export-all-symbols
