Apparently it is not as simple as that. The DLL and import library
were generated without warnings, ./configure detected amrnb and amrwb,
and MPlayer was built (although I currently have to disable vidix
and live555) but MPlayer crashed with:

gdb: kernel event for pid=3724 tid=2276 code=EXCEPTION_DEBUG_EVENT)
gdb: Target exception EXCEPTION_ACCESS_VIOLATION at 0x100057b9

Program received signal SIGSEGV, Segmentation fault.
0x100057b9 in dtx_dec () from c:\mingw\bin\amrnb.dll

There is nothing wrong with the 3GP file because I can play it with
a copy of MPlayer built the original way.
