[Bug java/30639] New: Can't compile java frontend on Linux x86_64 (SYS_sigaction undeclared)

This happens with gcc 4.1.1 too.

Linux 2.6.19 (pure x86_64 system without 32bit libraries)
glibc 2.5
gcc 4.1.1
/usr/include/asm contains the correct kernel x86_64 headers

I googled and found that SYS_sigaction is only defined on 32 bit arch... so why
is it looking for it? I don't pretend to compile 32 bit programs, so I don't
need it right?

Thanks

Then use --disable-multilib, otherwise x86_64 defaults to compiling the 32bit
libraries also.
