- Renamed IMAGE_BASE to LD_IMAGE_BASE_OPT. - Moved "-fcommon" to KLIBCREQFLAGS in scripts/Kbuild.klibc. - Remove "dash" warning fixes which have been upstreamed. - Conditionalize the inclusion of compiler flags by using the proper compiler name or "cc-option". - Added "-Werror" to "cc-option" to catch flags that cause warnings. - Retain

Hello! Can someone please help me in building debug version of klibc ? I've cloned git://git.kernel.org/pub/scm/libs/klibc/klibc.git , but failed to build it with debug info added "-g" to HOSTCFLAGS in Makefile, but $ make -j KLIBCKERNELSRC=`pwd`/../linux-2.6/usr still strips every debug symbol , and i'm failed to change scripts/Kbuild.klibc and Makefile to remove strip
