help : about option -fshort-enums

[Gaurav Gautam, Noida]

Hi,

The documentation about implementation of enumeration in gcc, at the following link on the gcc site says that.

"On some targets, -fshort-enums is the default; this is determined by the ABI." 

I want to know the list of targets on which this option is default.
Can some one help me regarding this?

Gaurav
