I also tried to compile the SP71 program. There were only 7 real errors.
There is the idiotic for-scoping that was wrong in VC6. In VC 6, if you
write
for (int i=0; i<n; i++) { }
then the i variable belongs to the outer block, whereas in C++ since
1998 it belongs to the for block. So shift this to
int i;
for (i=0; i<n; i++) { }
to get the same effect. Then there was an default-to-int static variable
without a type; even the compiler knew how to fix it:
SP71_lib.cpp:16155:9: error: C++ requires a type specifier for all
declarations
static column_counter = 0 ;
~~~~~~ ^
1 error generated.
and a missing comma in a sequence of declarations; I wonder how that
ever could compile.
Now it compiles on clang, but with 283 warnings, of course. Here's the diff:

Only in SP_new/: a.out
