Re: [sv-bc] `` macro token gluing operator

Hi,
I will be happy to add more questions on that.

- When `` is present inside an escaped text, is it part of escaped text, 
or still it will act as operator. For e.g.
`define x \a``b

Will it be \ab , or \a``b

Different tools behave differently.

Regards
Surya
