Source: ilmbase
Version: 2.2.0-3
Severity: normal

Currenly ilmbase fails to build on non-linux arch because of the following 
try-compile. ilmbase checks for an old bug in GNU libc

[...]
//
// Ugly, the mxcsr isn't defined in GNU libc ucontext_t, but
// it's passed to the signal handler by the kernel.  Use
// the kernel's version of the ucontext to get it, see
// <asm/sigcontext.h>
//

#include <asm/sigcontext.h>
[...]

This code path is only executed when the following autoconf step fails:

AC_MSG_CHECKING(for fpe support handling)
control_register_support="no"
AC_TRY_COMPILE([
#include <stdint.h>
#include <ucontext.h>
],[
    ucontext_t ucon;
    uint32_t mxcsr = ucon.uc_mcontext.fpregs->mxcsr;
    uint16_t cw    = ucon.uc_mcontext.fpregs->cwd;

],
AC_DEFINE(ILMBASE_HAVE_CONTROL_REGISTER_SUPPORT) control_register_support=yes)
AC_MSG_RESULT($control_register_support)

If I check online, it appears that ilmbase compile and runs nicely on FreeBSD, 
therefore ucontext.h does not seems linux specific after all:
