wok-4.x view coreutils/stuff/sigcontext.h @ rev 7499
Made all firefox-langpack copy files right. Looks like mv can't move folders even with -f option. Used a cp -af then rm -rf instead.

10 * The first part of "struct _fpstate" is just the normal i387
11 * hardware setup, the extra "status" word is used to save the
12 * coprocessor status word before entering the handler.
13 *
14 * Pentium III FXSR, SSE support
15 * Gareth Hughes <gareth@valinux.com>, May 2000

17 * The FPU state data structure has had to grow to accommodate the
18 * extended FPU state required by the Streaming SIMD Extensions.
19 * There is no documented standard to accomplish this at the moment.
