Hello,
with this version of gcc which is default in ubuntu 12.10:
$ arm-linux-gnueabi-gcc -v Using built-in specs.

u-boot "true" and "false" hush commands are copiled incorrectly in uboot v2013.04-rc2 (c8142633e169665b246352918df5b76fd243bb71)
when I run help in u-boot it show:
# help 0 - do nothing, unsuccessfully 1 - do nothing, successfully ? - alias for 'help' base - print or set address offset ...
Instead "0" and "1" there should be "false" and "true" command.
This happen when stdbool.h from C99 compiler is included in cmd_test.c and then true and false macros are expanded to 1 and 0. Quick fix for this is adding #undef before U_BOOT_CMD:

+#undef true U_BOOT_CMD( true, CONFIG_SYS_MAXARGS, 1, do_true, "do nothing, successfully",
Without above patch and with gcc 4.7.2 it is not possible to use u-boot on Nokia RX-51, becuase it has true and false commands in preboot env.
Please fix this problem in u-boot v2013.04.
