xref: /OK3568_Linux_fs/buildroot/package/musepack/0003-include-fpu-control-with-glibc-only.patch (revision 4882a59341e53eb6f0b4789bf948001014eff981)
1Include <fpu_control.h> only on glibc systems
2
3The <fpu_control.h> header provides _FPU_*() macros, which the
4Init_FPU() function uses only on i386, and only when they are
5defined. Since <fpu_control.h> is not available, this causes a build
6failure with C libraries such as musl. By simply including
7<fpu_control.h> explicitly on glibc systems, we avoid the build
8failure, since mpcenc.c already conditionally uses the <fpu_control.h>
9macros only if they are defined.
