gnu make question

[Trey Jackson]

All,

Is it possible to undefine a make variable?
Not just set it to an empty string, but actually undefine it?

I can't find anything in the documentation, this mailing list archive,
or anything like that....

Perhaps there's a good reason to not have it?


i.e.

,----------------
| MYVAR = value
| 
| ifdef MYVAR
|   # do something i want
| endif
| 
| 
| undef MYVAR
| 
| ifdef MYVAR
|   # skip this
| endif
`----------------



Any help is appreciated,

thanks.
