this script please

same error

Ok... I solved this problem by myself....

Next is little solve history:

So... The main reason "why this thing didn`t compile" is that gcc-6.3.0 CAN`T BE COMPILED FROM SOURCE...

in gcc-6.3.0 we have next error:

../../gcc/ubsan.c:1474:23: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
       || xloc.file == '\0' || xloc.file[0] == '\xff'
                       ^~~~
Makefile:1085: recipe for target 'ubsan.o' failed

that means "I CAN`T"...

But, this doesn`t mean that you can`t compile it
There is 2 ways for solving that:

    1) The first one is "change the code":
        You need to "untar" the archive and find file "gcc-6.3.0/gcc/ubsan.c"

        In gcc in file "gcc/ubsan.c" on line 1473 we have next 4 lines:
                     if (xloc.file == NULL || strncmp (xloc.file, "\1", 2) == 0
                           || xloc.file == '\0' || xloc.file[0] == '\xff'
                           || xloc.file[1] == '\xff')
                         return false;
         You need to change the " xloc.file == '\0' " to " xloc.file[0] == '\0' "
         than archive it back and change in "gcc" and "libstdc++" scripts md5sum hash to new one (u can get by "md5sum" command)
         and after that its gonna work (i made this way)
     2) The second is "change the link source":
          If you don`t need to make "way #1" every time you can make this:
               you need to change link and md5sum in "gcc" and "libstdc++" to (at least) gcc with version 6.4.0
          This way you can use only 1 time and feel free from problems...

Little message to lfscript developers:
  when will be next revision of lfscript? last release in 2019.01.27 is 20170513???
