Thanks for the report; I'll take a look into getting that done this week.

Odd parsing of identifier in define

Hi guys,

define( `def' )
ifdef( `def', defined, not defined )
->
not defined

On examining the debug output, it seems that the identifier is saved as `def ' instead of `def'. What
confuses m4 is the trailing space. The problem disappears if the trailing space is removed i.e. 

define( `def')

Is this a bug or a feature?

1.4.14 on Windows
1.4.16 on Linux.

regards

Yep.

Feature.  Trailing whitespace is always significant.  _Only_ unquoted 
leading whitespace gets trimmed when collecting macro arguments.
