Has anyone successfully built glibc with "-mthumb-interwork"?
I've been working with it for a couple of hours, with
glibc 2.2.5
gcc 3.0.3
binutils 2.11.2
I applied the following patch to glibc to make it compile without thumb
***********
diff -ur glibc-2.2.5.orig/sysdeps/unix/sysv/linux/configure

but I can't get it to compile with thumb. Here is a snippet of code gcc
generates

bl mcount

mov r5, r0
ldr r3, [r5]

of course GNU assembler doesn't like the "mov\tip, lr" line
