glibc 2.3.3 patches for mips?

Anyone here using glibc 2.3.3 on mips? I had trouble using crosstool to build a gcc_3.3.3-glibc_2.3.3 combination. gcc_3.3.3-glibc_2.3.3 seems to have built fine, although I haven't done much testing of the binaries...

If anyone is using glibc_2.3.3, what patches (if any) did you use to get it going?

Thanks,

John

I am not using crosstool, but have gcc-3.3.1 based cross compiler build of glibc-2.3.3 that is running well.

Use binutils 2.15.

This all for mipsel-linux target.

Attached are my glibc-2.3.3 patches. Still having problems getting gcc-3.4.2 to build it, so if anybody has the magic answer for that...

David Daney.
