Hi Alexander, One way is this trick: 1. Rename cc1plus.exe to cc1plus_real.exe 2. Create a shell script called cc1plus, use it to bootstrap gdb, refer to cc1plus_real.exe, passing along "$@" command line parameters as appropriate. There's probably other good tricks as well. This "low-jack" technique works well on Unix, and probably will work in the Cygwin environment too. Good luck, --Eljay
