Similarly, I get this error on mingw in C++ mode:
../gllib/sys/ioctl.h:318: error: `ioctl' was not declared in this scope
and, once this is fixed:
g++-3 -mno-cygwin -L/usr/local/mingw/lib -o test-sys_ioctl-c++.exe
test-sys_ioctl-c++.o ../gllib/libgnu.a
../gllib/libgnu.a(ioctl.o): In function `ioctl':
/home/bruno/testdir3/gllib/ioctl.c:65: undefined reference to
`_ioctlsoc...@12'
../gllib/libgnu.a(ioctl.o): In function `ioctl':
/home/bruno/testdir3/gllib/w32sock.h:34: undefined reference to
`_wsagetlaster...@0'
Here I'm solving the first problem. The second one is common to all sockets
functions:
- Why don't have modules 'accept' ... 'shutdown' not have a
"Link: $(LIBSOCKET)" section?
- Why don't the functions 'accept' ... 'shutdown' initialize the ws2_32
library upon first use?

ioctl: Fix C++ test error on mingw.
* lib/ioctl.c (ioctl): Renamed from rpl_ioctl.
* lib/sys_ioctl.in.h (ioctl): When SYS_IOCTL_H_HAVE_WINSOCK2_H is 1,
use _GL_FUNCDECL_SYS, not _GL_FUNCDECL_RPL.
