Sorry for my poor English and poor information.

Before meeting this broken, I used U-boot-v2009.06, and no compiling errors.

Then I changed to U-boot-v2009.08, and lib_generic/zlib.c is broken because of finding no stdio.h and fprintf function when debug function enabled. So I checked the source code and found that the DEBUG macro in zlib.c conflict with my global DEBUG macro, and the DEBUG of zlib.c in U-boot-v2009.06 is DEBUG_ZLIB.

And I'm thinking whether it is right to add a global DEBUG macro in PLATFORM_CPPFLAGS.

Thanks.

I'm not sure what exactly you want to tell us. If you see a problem and have a fix for it, then please prepare a patch. See http://www.denx.de/wiki/U-Boot/Patches for details.
