I did not understand why gcc would not run.

Then what?

You mean why it compiled? Because GCC permits more things than ANSI C++
(consider of it as system extensions). All compilers permit more stuff,
but for code to be guaranteed to be portable, must be ANSI compliant.

All compilers have a limit of stack. In DOS times it was 64 K. Now in
Windows it is 1-2 MB. With the updated code i sent to the list here is
info for thhe stack on my XP system:


MINGW:

"C:\mingw\bin\g++.exe" -O3 -march=i686 -ansi -pedantic-errors -o temp
"temp.cpp":

Allocated approximately 2002 KB of stack before i die

C:\c>



BC++:

"bcc32" -6 -O2 "temp.cpp"


Allocated approximately 1006 KB of stack before i die

C:\c>


So as you see MINGW/GCC provides one of the largest stack!

No, MINGW produces Win32 applications (even console programs do not run
above pure DOS).

No it isn't. It is a compiler issue.
