Hello,
I have three suggestions that could help you.
1) Try to search in the forum about Borland compiler. There were some posts already about that compiler. May be one of them could help you solve your problem.
2) Check if you have set correctly all the include/link directory in C::B.
3) Try the Borland compiler website. May be you have to do something special to make it works.
Hope this would help.
Michael
