Re[1]: [cedet-semantic] Not all comments ignored when parsing C

[Eric M. L. <er...@si...>]

Hi,

  You have found a curious side-effect of the lexical short-cut I used
to handle complex expressions.  Basically, the lexical stage skips
everything inside { } or ( ), and they are identified as full
syntactic expressions.  If the parser must know what is inside, it
asks (argument lists, for example).  In the case of expressions, I
wasn't ready to write a full expression parser, so I just captured
the plain-text of that expression into the value.

  It is probably possible to strip out comments here.  It is near line
1030 in c.by.
