- Subject: error: forward declaration of `struct bit::bitObject'
Dear Listers,
I posted this question on the GCC-help list but maybe someone here can give
me some advice on how to proceed also.
I am working on a VC++ to gcc conversion, and I'm facing some problems that
I cannot find the answers for. I'm working on a Windows XP machine with
cygwin installed and as IDE I'm using Ecplipse. The GCC complier I am
working with is:
>gcc (GCC) 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125) Copyright
>(C) 2004 Free Software Foundation, Inc. This is free software; see the

I'm getting the error message: error: forward declaration of `struct
bit::bitObject' and I cannot find the problem.
I hope that someone can point me in the correct direction.
With best regards,
Roel Bindels
