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 CFLAGS='-g -O2 -DFD_SETSIZE=256'

mkmf check for socklen_t:

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

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

"gcc -I../.. -I../../../../../../ruby -I../../../../../../ruby/ext/socket -I.   -g -O2 -DFD_SETSIZE=256    -c conftest.c"
conftest.c:5:19: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'conftest_type'
conftest.c:6:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'conftestval'
checked program was:
/* begin */
1: #include <windows.h>
2: #include <winsock.h>
3: 
4: /*top*/
5: typedef socklen_t conftest_type;
6: static conftest_type conftestval[sizeof(conftest_type)?1:-1];
/* end */

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

Checking rbconfig.rb COMMON_HEADERS:

CONFIG["COMMON_HEADERS"] = "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 generated by the configure process.

GCC been used:
gcc (tdm-1) 4.5.1
