2016-04-03kbuild: Fix gcc -x syntaxJean Delvare
The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

2016-04-03kconfig: fix check-lxdialog for DLL platformsYaakov Selkowitz
Import libraries on Cygwin and MinGW/MSYS use the .dll.a suffix, so checking this suffix is necessary to make sure ncurses will still be found when built without static libraries.

2016-04-03kconfig: check ncursesw headers first in check-lxdialogYaakov Selkowitz
Commit 8c41e5e363db55d91aa3b1cdce4ab02ad9821de7 added a check for ncursesw/curses.h for the case where ncurses and ncursesw are build separately but only one is installed. But if both are installed, the headers ncurses/curses.h and ncursesw/curses.h differ, and since libncursesw will be found first, so should ncursesw/curses.h.

2016-04-03kconfig: fix menuconfig on debian lennyJunio C Hamano
In 60f33b8 (kconfig: get rid of stray a.o, support ncursesw, 2006-01-15), support to link menuconfig with ncursesw library was added. To compute the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow ncursesw to be used as a replacement ncurses. However, when checking what header file to include, we do not check /usr/include/ncursesw directory. Add /usr/include/ncursesw to the list of directories that are checked. With this patch, on my Debian Lenny box with libncursesw5-dev package but not libncurses5-dev package, I can say "make menuconfig".

2016-03-30applet_tables: save space by removing applet name offsetsRon Yorston
The array applet_nameofs consumes two bytes per applet. It encodes nofork/noexec flags suid flags the offset of the applet name in the applet_name string Change the applet_table build tool to store the flags in two separate arrays (applet_flags and applet_suid). Replace applet_nameofs[] with a smaller version that only stores a limited number of offsets. This requires changes to the macros APPLET_IS_NOFORK, APPLET_IS_NOEXEC and APPLET_SUID. According to Valgrind the original find_applet_by_name required 353 cycles per call, averaged over all names. Adjusting the number of known offsets allows space to be traded off against execution time: KNOWN_OFFSETS cycles bytes (wrt KNOWN_OFFSETS = 0) 0 9057 - 2 4604 32 4 2407 75 8 1342 98 16 908 130 32 884 194 This patch uses KNOWN_OFFSETS = 8. v2: Remove some dead code from the applet_table tool; Treat the applet in the middle of the table as a special case. v3: Use the middle applet to adjust the start of the linear search as well as the last applet found. v4: Use an augmented linear search in find_applet_by_name.
