package/musepack/0003-include-fpu-control-with-glibc-only.patch

   1 Include <fpu_control.h> only on glibc systems
   2
   3 The <fpu_control.h> header provides _FPU_*() macros, which the
   4 Init_FPU() function uses only on i386, and only when they are
   5 defined. Since <fpu_control.h> is not available, this causes a build
   6 failure with C libraries such as musl. By simply including
   7 <fpu_control.h> explicitly on glibc systems, we avoid the build
   8 failure, since mpcenc.c already conditionally uses the <fpu_control.h>
   9 macros only if they are defined.
