[ARM] EABI and the default to short enums

Hello,

the default ARM EABI configuration uses short enums by default (from 
"gcc/config/arm/arm.c":

/* AAPCS based ABIs use short enums by default.  */

static bool
arm_default_short_enums (void)
{
  return TARGET_AAPCS_BASED && arm_abi != ARM_ABI_AAPCS_LINUX;
}

This causes a major headache for me since some libraries assume that sizeof(any 
enum) > 1, e.g. the standard XDR library.  Is the only possible way to disable 
short enums to set the ABI to ARM_ABI_AAPCS_LINUX?  Which side effects does 
this have?

Have a nice day!
