[-- Attachment #1: Type: text/plain, Size: 310 bytes --]

The attached patch fixes a crash if gfortran encounters a nested
function when -mhotpatch is enabled.  (It slightly improves the
warning message too.)

This patch affects s390 only.  Andreas Krebbel will commit the
patch soon, if there are no objections.

Ciao

	* config/s390/s390.c (s390_asm_output_function_label):
	fix crash caused by bad second argument to warning_at() with -mhotpatch
	and nested functions (e.g. with gfortran)
