No shared library under x86_64-w64-mingw32?

[Luis Lavena]

Hello,

I'm attempting to build libffi 3.0.10 with mingw64 compiler (4.6.1,
tdm64-1 build) using the following parameters:

sh configure --host=x86_64-w64-mingw32 --enable-shared

However, when installed, it results only in lib/libffi.a and libffi.la
with no shared object generated (dll) or implib for it (libffi.dll.a)

When build with normal TDM (mingw.org, GCC 4.6.2) it properly generate
the shared object.

Trying to figure out the reason for that, I'm missing something?

Thank you.
