Hello Sebastian,

  I have executed the following test case:

	arm-none-eabi-gcc -mthumb -march=armv7-m -c -g conftest.c >results
	echo Result: \"$?\"

Where conftest.c had the following contents:

	/* confdefs.h */
	#define PACKAGE_NAME "newlib"
	#define PACKAGE_TARNAME "newlib"
	#define PACKAGE_VERSION "2.1.0"
	#define PACKAGE_STRING "newlib 2.1.0"
	#define PACKAGE_URL ""
	/* end confdefs.h.  */
	main ()
	  return 0;

The created "results" text file is empty.
The echoed result of \"$?\" is: "0".

A value of $? indicates that the previous command was successful. So what does the configure script with this value? Its always fun to debug configure scripts.
