RELOCATE_PROJECTROOT is AC_DEFINED in configure.ac, but currently has no effect as it doesn't appear in any AC_CONFIG_HEADER header. When packaged for Windows, we do not have a unix-style filesystem tree, where file needed by the X server can be found in fixed, absolute paths under the prefix (PROJECTROOT). Instead, the filesystem tree containing files needed by the X server and clients will be installed with the directory containing the X server executable as the root directory of that tree. (Typically, this will be in the Program Files directory, which does not have a fixed name, as it can be moved, localized, or added to to indicate x86 or x64 binaries) So, RELOCATE_PROJECTROOT is used to make a native Windows build of the X server look for various files (fonts, xkb data) in locations relative to the X server rather than at absolute paths, by translating those paths at run-time. Additionally the XKEYSYMDB, XERRORDB, XLOCALEDIR env vars checked by libX11 are set appropriately for clients started by the X server.
