This change makes it possible to combine Dylan libraries and all of their dependencies into a single unified executable using the -UNIFY build option. The unified executable will be stored in the sbin (static executables binary) directory of the personal-root target. * sources/jamfiles/posix-build.jam (SBINDIR): New global representing the destination directory for static executables. (UNIFYLINK): New global representing the command used to link the unified executable. (rule DylanLibrary): Create a unified executable target and a unified static library archive for each library. Rename the global _lib_$(_i) to _lflag_$(_i). (rule DylanLibraryFiles): Add library objects to the unified static library archives. (rule DylanLibraryLinkerOptions): Add linker options to the unified executable target, and store them so they can be added to some final executable that depends on the current library. (rule DylanLibraryCObjects): Add C objects to the unified static library archives. (rule DylanLibraryCSources): Add C compiled objects to the unified static library archives. (rule DylanLibraryUses): Collect library dependencies and linker options of used libraries and add them to the unified executable. (rule DylanLibraryClosure): Rename the global _lib_$(_i) to _lflag_$(_i). (rule UnifyArchive, actions UnifyArchive): Create static library archives. (rule UnifyEXE, actions UnifyEXE): Create static executbles. (rule FLIBName): Rule for naming static archives. (rule FULIBName): Rule for naming static archives built to contain all executables of a library. * sources/jamfiles/*-linux-build.jam (rtclibs): Add -ldl since the spy interface code in the dylan library references dlopen(). * sources/jamfiles/shared-darwin-build.jam (actions UnifyEXE): Add an override for macOS support.
* configure.ac: Update AC_INIT to 2022.1pre * sources/lib/release-info/common-info.dylan ($release-version): Update to 2022.1pre. * documentation/release-notes/source/2021.1.rst: Rename from 2022.1.rst.
