[aspectc-user] Problem with doing simple weaving on FreeBSD

[Olaf Spinczyk]

Hi Carsten,

the reason is that the ac++ parser treats __wchar_t as a keyword. It is 
equivalent with wchat_t.

At the moment I don't remember the reason. Either some g++ version or 
VC++ has to treat it as a keyword, too. Thank you for reporting this 
problem. We'll look into it.

Meanwhile you might try the command line option "-D__wchar_t 
no__wchar_t" as a workaround.

- Olaf
