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