Thank you very much Diego for your help.

Here are the additional details that might help you
to understand better the problem:

Configure invocation (both produce the same error):

bash ./configure --disable-static --enable-shared --enable-mingw32 --prefix=/usr
or
./configure --disable-static --enable-shared --enable-mingw32 --prefix=/usr

--

Error message in console (error comes from linking ld.exe (see
the last lines of the config.err file below)):

gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --cross-compile option.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from SVN.  If the latest version fails, report the problem to the
ffmpeg-devel at mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.
