Re: Problems again with Pango and CYGWIN

[Behdad Esfahbod <behdad behdad org>]

Hi,

I fixed one of the bugs, but the one about non-default constructors seems to 
be an issue with old gcc only.  The base class in question has no constructor. 
 Googling suggests that many other projects have hit the same issue with no 
resolution.
