Re: egcs 980315 bug on powerpc-unknown-linux-gnulibc1

[Franz Sirl <Franz dot Sirl-kernel at lauterbach dot com>]

Elliott,

I think for globc.c you still need the case-folding patch from Geoff's
patch set. It's not checked in yet to egcs.

(Jeff, should I send in Geoff's test case as an additional test for
gcc.c-torture/compile?)

Bye,
Franz.
