The bash commands below the ==== line should work to build a 2.6.30 
kernel for i386 if you have the full cygwin 1.7 install

This assumes you have an obj and src directory with the expanded tar 
ball for binutils, gcc, and the kernel versions used here

The only source change you will need to make is to add the following 
defines to ~scripts/mod/modpost.h after the include of elf.h

This is needed because the cygwin 1.7 elf.h does not have these defines 
which are available in the linux elf.h for modpost


#define R_386_32        1
#define R_386_PC32      2
#define R_ARM_ABS32             2
#define R_ARM_PC24              1
#define R_MIPS_26               4
#define R_MIPS_32               2
#define R_MIPS_HI16             5
#define R_MIPS_LO16             6
