Build tries to link binary (obj) file to executable (exe).
When CC, it calls CL compiler, which results to total nonsense:

cl 
-out:/cygdrive/r/buildroot/jdk/btnative/genSocketOptionRegistry/genSocketOptionRegistry.exe 
/cygdrive/r/buildroot/jdk/btnative/genSocketOptionRegistry/genSocketOptionRegistry.obj 

cl : Command line warning D9035 : option 'o' has been deprecated and 
will be removed in a future release

it doesn't event know -out parameter and tries to go with -o and file 
"ut:..." so this is totally wrong. Also "genSocketOptionRegistry.obj" 
file is already binary.


When LD, then "link" is used and binary obj is correctly linked to 
executable:

link 
-out:/cygdrive/r/buildroot/jdk/btnative/genSocketOptionRegistry/genSocketOptionRegistry.exe 
/cygdrive/r/buildroot/jdk/btnative/genSocketOptionRegistry/genSocketOptionRegistry.obj

However, as Alex pointed out[1], the patch breaks cross-compilation :/
