Before this commit, compilation of `pcm_dmix` causes warnings "ignoring
return value" for `fgets` operations:
~~~~
pcm_dmix_i386.c:108:5: warning: ignoring return value of 'fgets', declared
with attribute warn_unused_result [-Wunused-result]
fgets(line, sizeof(line), in);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~
This commit fixes the warnings.
