+Subject: [PATCH] Use <fenv.h> when available instead of <fpu_control.h>
+
+musl libc (http://musl-libc.org lack the non-standard <fpu_control.h>
+header, which is used in src/os/linux/{i386,x86_64}/init.c files to
+setup the floating point precision. This patch makes it use the
+standard C <fenv.h> header instead when available.
+
+Original patch at Felix Janda at
+https://sourceforge.net/p/jamvm/patches/6/, adapted to still use
+<fpu_control.h> if <fenv.h> is not provided.
