I'm using intel C++ 7.1 on windows. A weird thing is that I can only have xilink work under the "build environment for IA32 application" console coming with the installation. E.g. if I type "xilink" in a normal command console or under cygwin, it'll display the help and a last sentence:
xilink: error: can't run 'link'; inaccessible drive or directory in PATH.
The installation already modified my env settings(PATH, INCLUDE, LIB), I can resolve xilink, icl, cl, link etc. perfectly well.
