   4 Subject: [PATCH] output_alsa: use mallopt() only on glibc
   5
   6 The musl C library does not provide the glibc specific mallopt()
   7 functionality, so use it only when __GLIBC__ is defined.
   8
   9 uClibc pretends to be glibc by defining __GLIBC__, but it implements
  10 mallopt(), so it works fine.
