Update of /var/cvs/uClibc/libc/sysdeps/linux/mips/sys
In directory nail:/tmp/cvs-serv14560/libc/sysdeps/linux/mips/sys
Modified Files:
user.h
Log Message:
It turns out that asm/reg.h is missing from the 2.6.x kernel headers,
which prevents libthread_db (used by gdb) from compiling. Include a
copy within include/sys/user.h for mips, per what was done in glibc.
