Although they both are ver similar drivers that invoke the sub-parts of the toolchain (compiler, assembler, linkers), and in fact either one can recognize the extension of a file and pass it to the right language version of the compiler, the g++ driver also knows to add the appropriate -L and -l options for linking against the standard C++ libraries automatically. cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
