[U-Boot] Problems compiling u-boot under Cygwin

[Brad M. <max064@yahoo.com>]

Hi.  I'm a first time u-boot builder, and first time poster.  I'm looking for some help building u-boot for the Atmel at91sam9260ek dev board.

Background: building u-boot (v2010.03) on WindowsXP with Cygwin.  PATH and CROSS_COMPILE env vars set appropriately.  Cygwin base package installed, plus 'make' and 'gcc'.  I've tried three different tool chains: CodeSourcery Lite, GNUARM, and YAGARTO, each giving me different errors.  I have also tried several flavors of make, those too influence the build.  I'm not sure which is giving me the best performance.

In all cases, "make distclean" and "make at91sam9260ek_config" work fine.

Below are highlights of some of the "make all" results.  I'll take any help on any one of the tool chains (please do not feel obligated to comment on all of them, only the one I'll likely get the easiest success with).

But any help is greatly appreciated.

Thanks in advance,
Brad.
