compilation errors with gcc 8.3

[streaps]

I tried to compile Maximus (v3_03b) on a Raspberry Pi running Raspian / Debian 10 Buster and gcc 8.3. As expected there were a few compilation errors. As I'm not a C(++) programmer I used Google and trial and error to get it compile without errors, but I have no idea what are the corrtect changes to fix these errors. My first goal was to figure out if it compiles at all. It looks like minor problems which should be easily fixable (by someone with a little bit more C(++) experience than me).

btree/dbase.cc:32:10: fatal error: new.h: No such file or directory
 #include <new.h>
          ^~~~~~~

changed <new.h> to <new>

slib/progprot.h:56:11: error: expected unqualified-id before ‘nullptr’
 int _fast nullptr(void);
           ^~~~~~~

renamed nullptr to slib_nullpointer

sqafix/sqauti.c:1775:8: error: wrong type argument to unary exclamation mark
    if (!argptr) va_start(argptr, pszFormat);
        ^

removed if (!argptr)

mex/mex_tab.y:516.48-49: error: $$ for the midrule at $2 of ‘else_part’ has no declared type
                                 { ElseHandler(&$$); }
                                                ^~

changed &$$ to &$<elsetype>$

this fork is dead; there is a fork here: https://github.com/fidosoft/maximus that is a little more up to date.

Note, you should use 32bit flags when compiling. There is a ton of code that is not 64bit clean.
