HasGcc2 Set to YES to build with gcc version 2. Both this option and HasGcc look for a compiler named gcc , but HasGcc2 will cause the build to use more features of gcc 2, such as the ability to compile shared libraries. This is a directory where programs will be found even if PATH is not set in the environment. It is used, for example, when connecting from a remote system via rsh . The rstart program installs its server in this directory.
Some systems require the X server to run as root to access the devices it needs.
If you are on such a system and will not be using xdm , you can set this variable to YES to install the X server setuid to root. Causes Xlib and Xt to work around some bugs in older versions of Motif. Set to YES only if you will be linking with Motif version 1.1.1, 1.1.2, or 1.1.3. Setting this variable to YES allows illegal XtGetValues requests with NULL ArgVal to usually succeed, as R5 did. Some applications erroneously rely on this behavior.
