>Description:

The following tests are failing on mips-sgi-irix6.5 with -mabi=64 with the error "character constant too long"

gcc.c-torture/compile/970214-1.c
gcc.c-torture/execute/970214-2.c
gcc.c-torture/execute/widechar-1.c
gcc.c-torture/execute/widechar-2.c
gcc.dg/c99-init-1.c
gcc.dg/cpp/if-2.c
gcc.dg/cpp/lexstrng.c
gcc.dg/cpp/paste2.c


The shortest test failing is gcc.c-torture/compile/970214-1.c

#include <stddef.h>
#define L       264
wchar_t c = L'X';

Preprocessed, this becomes

# 1 "/exd4/billingd/src/gcc/gcc/testsuite/gcc.c-torture/compile/970214-1.c"
# 1 "/exd4/billingd/obj/gcc/gcc/include/stddef.h" 1 3
# 147 "/exd4/billingd/obj/gcc/gcc/include/stddef.h" 3
typedef int ptrdiff_t;
# 199 "/exd4/billingd/obj/gcc/gcc/include/stddef.h" 3
typedef unsigned int size_t;
# 287 "/exd4/billingd/obj/gcc/gcc/include/stddef.h" 3
typedef long int wchar_t;
# 2 "/exd4/billingd/src/gcc/gcc/testsuite/gcc.c-torture/compile/970214-1.c" 2

wchar_t c = L'X';
