This question would be better asked on the mailing list
gcc-h...@gcc.gnu.org rather than gcc@gcc.gnu.org. The gcc@ mailing list
is for issues related to the development of gcc itself. Please take any
followups to gcc-help. Thanks.
You can use -fno-short-enums. However, see the note about ABI
compatibility in the -fshort-enums doc.
