alsa-project/alsa-lib issue #348 was opened from ajakk:

When configured with raw MIDI support, `control.h` declares:

``` int snd_ctl_ump_endpoint_info(snd_ctl_t *ctl, snd_ump_endpoint_info_t *info); int snd_ctl_ump_block_info(snd_ctl_t *ctl, snd_ump_block_info_t *info); ```

However, it doesn't seem that the `snd_ump*` types are defined here, and this results in build failures in applications compiling against alsa-lib-1.2.10. [For example](https://bugs.gentoo.org/913521) ([build log](https://913521.bugs.gentoo.org/attachment.cgi?id=869245)):
