Hi,
a note regarding this fix:
2010-04-11 Vladimir Serbinenko <...>
Fix cygwin compilation.
* configure.ac: Define NEED_REGISTER_FRAME_INFO.
* include/grub/misc.h (__register_frame_info)
[NEED_REGISTER_FRAME_INFO && !UTIL]: New export.
(__deregister_frame_info) [NEED_REGISTER_FRAME_INFO && !UTIL]:
Likewise.
* kern/misc.c (__register_frame_info)
[NEED_REGISTER_FRAME_INFO && !UTIL]: New empty function.
(__deregister_frame_info) [NEED_REGISTER_FRAME_INFO && !UTIL]:
Likewise.

The *_frame_info symbols are set undefined to force linkage of the
libgcc_s shared library or dll.
This can be prevented by TARGET_LDFLAGS=-static-libgcc. To build from
grub-1.98 tarball on Cygwin, run configure with this argument.
May also be necessary on other build platforms when -shared-libgcc is
the default. It may be possible simply set -static-libgcc unconditionally.
