Warnings while compiling glibc-2.3.1 for cris


Hi,

during cross compiling glibc-2.3.1 for cris with gcc-2.3.2 I get the following warnings (extracted with "fgrep -i warning compile_glibc.out | sort -u"):

../linuxthreads/sysdeps/cris/pspinlock.c:31: warning: passing arg 1 of `testandset' discards qualifiers from pointer target type

Does any of those indicate that something serious is wrong?
