I get the following linker error
when I run make game.exe:

cd d:/research/2004/djgpp-game/
make game.exe
c:/djgpp/bin/gpp.exe game.o -o .exe -lstdcxx -lm
game.o(.text+0x3b):game.cc: undefined reference to `__alloca'
collect2: ld returned 1 exit status
make: *** [game.exe] Error 1

Here is my Makefile:

BIN=c:/djgpp/bin

%.run: %.exe
./$*.exe

game.exe: game.o
$(BIN)/gpp.exe $^ -o $*.exe

Here is the file that I am trying to link: (game.cc)

#include <iostream>
using namespace std;

int main()
{
cout << "Welcome to game.exe!\n";
}

This problem did NOT exist with an earlier version of Djgpp
that I had installed. The problem only became evident after
I installed the following zip files:

bnu214b.zip
djdev203.zip
faq230b.zip
gcc333b.zip
gpp333b.zip
mak3791b.zip
txi47b.zip

I have read the Djgpp FAQ and it doesn't mention my problem.
Please help me to fix the linker error!
