 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:

 mkmf check for socklen_t:

 checked program was:

 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
