730 dnl -----------------
731 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
732 dnl character-strings.
734 dnl It is ambiguous because the specification accommodated the pre-ANSI
735 dnl compilers bundled by more than one vendor in lieu of providing a standard C
736 dnl compiler other than by costly add-ons. Because of this, the specification
737 dnl did not take into account the use of const for telling the compiler that
738 dnl string literals would be in readonly memory.
740 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
741 dnl let the compiler decide how to represent Xt's strings which were #define'd.
742 dnl That does not solve the problem of using the block of Xt's strings which
743 dnl are compiled into the library (and is less efficient than one might want).
745 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
746 dnl when compiling the library and compiling using the library, to tell the
747 dnl compiler that String is const.

3329 dnl Attempt to determine the appropriate CC/LD options for creating a shared

3334 dnl the build-tree, i.e., by making use of the libraries that are compiled in
3335 dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
3336 dnl shared library since that can lead to unexpected results at runtime.
3337 dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
3338 dnl libraries are compiled in ../../lib
3340 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
3341 dnl to install symbolic links to the rel/abi versions of shared libraries.
3343 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
3344 dnl version when making symbolic links.
3346 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
3347 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
3348 dnl (ex: libncurses.so.<ver>).
3350 dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
