Hi, As I am fixing some of the C++ ports for GCC 3.2, I found a problem with lex. The following patch is required for lex to generate code which can compile with GCC 3.2. It applies to /usr/src/usr.bin/lex

Under gcc 2.95, <iosfwd> forward declares istream as "class istream;" and under gcc 3.2, <iosfwd> forward declares istream as the typedef. The "using namespace std;" is required because in gcc 3.2, istream is in the std namespace. In gcc 2.95, this line will be benign. -- Craig Rodrigues http://www.gis.net/~craigr [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
