Oops, I didn't realise Martin had already done that work :-(

Martin and I had different ideas about which files should be converted to 
Unix line endings and which shouldn't:

File				Martin	Me (my reason)
----				------	--------------
boxbackup.sln (VS project?)	Yes	No (does it still work with VS?)
lib/win32/bbackupd.conf		No	Yes (cross platform compatibility)
lib/win32/emu.{cpp,h}		No	Yes (converted all .cpp files)
lib/win32/ReadMe.txt		No	Yes (converted all .txt files)
lib/win32/win32test.cpp		No	Yes (converted all .cpp files)

I don't have any real objections to going along with Martin's decisions, 
provided that the project files still work in VS and we don't mind having 
inconsistent line endings between lib/win32 and the rest of the project, 
but I would be interested to hear what others think.

I would like to clean up the comments and line lengths before this gets 
merged, since I'm certain you won't allow me to change them afterwards :-) 
Any objections?

I also see that Martin has removed boost from the project, but I don't see 
any changes to the build files to replace the boost regex library which 
Nick used.

I think we must have regex support on win32. Would you have any objections 
to including a copy of Henry Spencer's regex library? 

The license is BSD-like with attribution clause, so we would have to 
acknowlegde him in the docs, but apart from that I hope it will not 
conflict with your license.

I agree completely, and would like to go ahead and do so.

I will do that as well as I can, but reviews of my changes would be 
greatly appreciated.

No worries, I'm glad that it's open now. The win32 port was never going to 
be easy to merge into a project with long release cycles.

Free for a year is OK by me. I just hope it doesn't preclude me from 
working on GPL code.

Absolutely. I want people to be able to build Box and Boxi on Windows 
using free tools, although I would also like to give them the option of 
using VS if they prefer.

Don't the existing scripts require a decent shell (>> cmd.exe) and Perl? 
Then MinGW wouldn't be enough by itself, you would probably need Cygwin to 
run them.

I'm looking at using a free (as in beer) Windows IDE called Chinook, which 
comes with wxWidgets support and the MinGW tools. I think it would be 
quite easy to auto-generate the Chinook project file from Perl, maybe even 
a cmd.exe batch file would do it.

Will do.

Cheers, Chris.
