I have the problem while configuring HTTrack on FreeBSD 
4.9:

$ ./configure --prefix=$HOME/httrack
.
.
.

checking for long... yes
checking size of long... 4
checking for long long... yes
checking size of long long... 8
checking long long printf format... ./configure.lineno: 
8852: Syntax error: Bad fd number

I know that this problem has already appeared 
(http://forum.httrack.com/readmsg/4340/index.html), but I 
don't know the solution.
