Lame with libsndfile -- errorlevel

When I run a copy of Lame I downloaded from Rarewares, and attempt to encode a file that's not supported, the program returns a non-zero value, showing that there was an error.

Code: [Select]
c:\Media\Flac>lame metaflac.exe
Warning: unsupported audio format

c:\Media\Flac>echo %errorlevel%
1

c:\Media\Flac>


Running the copy of Lame from that includes the libsndfile library, though, it will encode anything, and return 0, indicating success.

Code: [Select]
c:\Media\Flac>lame metaflac.exe
LAME 3.98.4 32bits (http://www.mp3dev.org/)
CPU features: MMX (ASM used), SSE (ASM used), SSE2

I'd really appreciate it if this copy of Lame threw an error, or at least returned a non-zero value, if it finds non-audio data. Is this feasible?

I'll take a look at it when I have a moment.
