Hello,

This seems to be the same issue as the closed report #1292

This is ruby_1_8_6 r29162 with #3883 patch applied.

Ruby configuration options were:

sh ../configure --enable-shared --with-winsock2 --disable-install-doc CFL=
AGS=3D'-g -O2 -DFD_SETSIZE=3D256'

mkmf check for socklen_t:

have_type: checking for socklen_t... -------------------- no

checked program was:

6: static conftest_type conftestval[sizeof(conftest_type)?1:-1];
/* end */

--------------------

Checking rbconfig.rb COMMON_HEADERS:

CONFIG["COMMON_HEADERS"] =3D "windows.h winsock.h"

Which could indicate even --with-winsock2 has been defined, winsock.h is =
been forced.

Find attached the full file and generated Makefile, also config.log gener=
ated by the configure process.

GCC been used:
gcc (tdm-1) 4.5.1
