compiling Windows code with g++ on Linux using msvcrt - good idea? if so, how do you do it?

I have a huge amount of Windows code that I'm porting to Linux.

Wine is turning out to be a read godsend, thank you guys!

Anyway, I've had tons of luck including the directory <wine_dir>/include/wine/windows in my include path. All my Windows types are there and everything is wonderful. I've even been able to link against the libraries by renaming, for example, to and using -lfoo on the g++ command line.

I actually haven't got all my functions defined so I don't know if this will actually run yet because the link isn't complete yet.

My first question is whether this will work. Will all my Windows functions with function declarations defined in the windows directory and code compiled into actually run?

Second, I see that some of the functions I want to use are actually defined by headers in the msvcrt directory. However, this directory contains tons of header files that my system (and gcc) also have under /usr/include and gcc's own directories. I understand that msvcrt is Windows lib c, but I wonder how I'm supposed to use it with gcc to compile? I've tried -nostdinc to gcc, but the number of errors I get is enormous.

It's not the end of the world if I can't use Wine's msvcrt, but if I could use it, it would define dozens more functions on which my program relies, or if its use was mandatory in order to get the functions implemented in to work, then obviously I wonder how I'm supposed to compile my Windows code with Wine to make everything work?

I'm sorry if this is a dumb question. I can't find a way to search the wine-devel mailing list other than with google and I can't find anything on there or other docs that answer this question, which I'm sure has been asked a million times and has a simple answer.

Thank you thank you,
