Hello!

 const char *dg_options[] = {
-"/* { dg-options \"%s-I%s\" } */\n",
+"/* { dg-options \"%s-I%s -Wno-abi\" } */\n",
 "/* { dg-options \"%s-I%s -mno-mmx -Wno-abi\" { target i?86-*-*
x86_64-*-* } } */\n",
 "/* { dg-options \"%s-I%s -fno-common\" { target hppa*-*-hpux*
powerpc*-*-darwin* *-*-mingw32* *-*-cygwin* } } */\n",
 "/* { dg-options \"%s-I%s -mno-mmx -fno-common -Wno-abi\" { target
i?86-*-darwin* x86_64-*-darwin* i?86-*-mingw32* x86_64-*-mingw32*
i?86-*-cygwin* } } */\n",

IMO, these should be converted to dg-additional-options.
