Fri Oct 3 13:43:18 1997 Ovidiu Predescu <ovidiu@net-community.com>
* Added support for linking with different types of a library,
depending on the flags you specify at the make time.
* which_lib.c: New file.
* config.h.in: New file.
* Makefile.in: Added rule to build and install the which_lib program.
* common.make: Added definition for WHICH_LIB_SCRIPT.
* rules.make: Added rules to process the libraries list and obtain a
new one based upon the debug, profile and shared variables.
* configure.in: Added checks for various header files needed to compile
the which_lib program.
* library.make: Added new variable LIBRARY_FILE_EXT.
* application.make: Replaced foreach with :.something=.someotherthing.
* bundle.make: Likewise.
* test.make: Likewise.
* tool.make: Likewise.
* config.make.in: Changed the hard-coded definition of ld to be $(CC).
Added definitions for INSTALL programs.
* configure.in: Added check for the INSTALL program.
* library.make: New target internal-distclean.
* rules.make: internal-distclean does not make first the clean target.
* target.make: Shared libraries under OS 4.x have the .so extension.

* ld_lib_path.sh: New file.

* Makefile.in: Install test.make.
Thu Oct 2 10:21:41 1997 Ovidiu Predescu <ovidiu@net-community.com>
* common.make.in: Remove the default library combo for OPENSTEP 4.x.
* configure.in: Add a default library combo for OS 4.x here.
