Update.
* stdlib/stdlib.h (drand48_data): Make available only for __USE_MISC. Rename elements to protect namespace. Change type and position of a and init element. * stdlib/drand48-iter.c: Don't handle unsigned short > 16 bit differently. Adjust for drand48_data change. Don't compute a here, it comes from drand48_data. * stdlib/lcong48_r.c: Don't handle unsigned short > 16 bit differently. Adjust for drand48_data change. Compute a here. * stdlib/srand48_r.c: Likewise. * stdlib/drand48.c: Adjust for drand48_data change. * stdlib/lrand48.c: Likewise. * stdlib/mrand48.c: Likewise. * stdlib/seek48.c: Likewise. * stdlib/drand48_r.c: Likewise. * stdlib/lrand48_r.c: Likewise. * stdlib/mrand48_r.c: Likewise. * stdlib/seed48_r.c: Likewise. Don't handle unsigned short > 16 bit differently. * stdlib/erand48_r.c: Don't handle unsigned short > 16 bit differently. * stdlib/jrand48_r.c: Likewise.
