I'm getting on i686-linux
FAIL: g++.target/i386/pr94185.C  -std=gnu++98 (test for excess errors)
This is because of a diagnostic that 4294967295 is unsigned only in ISO C90.
Adding U suffix fixes it and the testcase still ICEs with unfixed gcc and
passes with current trunk.

Tested on x86_64-linux with
check-c++-all RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} i386.exp=pr94185.C'
both using older GCC where it ICEs and current where it now all PASSes,
committed to trunk as obvious.

	PR target/94185
	* g++.target/i386/pr94185.C (l): Use 4294967295U instead of 4294967295
	to avoid FAIL with -m32 -std=c++98.
