Thomas E. Dickey 3faafb2efc ncurses 5.6 - patch 20070428 
+ add a configure check for gcc's options for inlining, use that to
  quiet a warning message where gcc's default behavior changed from
  3.x to 4.x.
+ improve warning message when checking if GPM is linked to curses
  library by not warning if its use of "wgetch" is via a weak symbol.
+ add loader options when building with static libraries to ensure that
  an installed shared library for ncurses does not conflict.  This is
  reported as problem with Tru64, but could affect other platforms
  (report Martin Mokrejs, analysis by Tim Mooney).
+ fix build on cygwin after recent ticlib/termlib changes, i.e.,
  + adjust TINFO_SUFFIX value to work with cygwin's dll naming
  + revert a change from 20070303 which commented out dependency of
    SHLIB_LIST in form/menu/panel/c++ libraries.
+ fix initialization of ripoff stack pointer (cf: 20070421).

dnl --------------
dnl --------------
dnl Attempt to determine the appropriate CC/LD options for creating a shared
dnl library.
dnl
dnl Note: ${LOCAL_LDFLAGS} is used to link executables that will run within the
dnl build-tree, i.e., by making use of the libraries that are compiled in ../lib
dnl We avoid compiling-in a ../lib path for the shared library since that can
dnl lead to unexpected results at runtime.
dnl ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared libraries
dnl are compiled in ../../lib
dnl
dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
dnl to install symbolic links to the rel/abi versions of shared libraries.
dnl
dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
dnl version when making symbolic links.
dnl
dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
dnl (ex: libncurses.so.<ver>).
dnl
dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.

dnl ---------------
dnl Try to get _XOPEN_SOURCE defined properly that we can use POSIX functions,
dnl or adapt to the vendor's definitions to get equivalent functionality,
dnl without losing the common non-POSIX features.
dnl
dnl Parameters:
dnl $1 is the nominal value for _XOPEN_SOURCE
dnl $2 is the nominal value for _POSIX_C_SOURCE
