Please try latest QEMU from git://git.qemu.org/qemu.git.
Some slirp related fixes were added recently.
I don't see any negative effects caused by -mms-bitfields
in my tests.

Title:
SLIRP still not working for win32
Status in QEMU:
New
Bug description:
SLIRP has not worked since 0.14.1 (broken since the move to
gthread/gio from the glib library which inherited -mms-bitfields on
MinGW32 breaking bit padding on TCP/UDP packets). Patches attempting
to reverse effects of GCC's -mms-bitfields do not seem to fix SLIRP.
Here is an example slirp debug log:
