+ fix some strict compiler warnings for abi6 and 64-bits.
+ use begin_va_copy/end_va_copy macros in lib_printw.c (cf: 20120303).
+ improve a limit-check in infocmp.c (Werner Fink):
+ for term-driver configuration, ensure that the driver pointer is
initialized in setupterm so that terminfo/termcap programs work.
+ amend fix for Debian #542031 to ensure that wattrset() returns only
OK or ERR, rather than the attribute value (report by Miroslav
Lichvar).
+ reorder WINDOWLIST to put WINDOW data after SCREEN pointer, making
_nc_screen_of() compatible between normal/wide libraries again (patch
by Miroslav Lichvar)
+ review/fix include-dependencies in modules files (report by Miroslav
Lichvar).
+ continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).
+ modify declaration of cur_term when broken-linker is used, but
enable-reentrant is not, to match pre-5.7 (report by Charles Wilson).
