prime.zip

With gcc13.1 finds 2 primes upto 1000000 :)

m68k-amigaos-gcc -O3 -mcrt=nix13 -o prime prime.c
vamos -v prime 1000000 1

With gcc6 finds the correct number 78498

vamos -v prime 1000000 1

the conversion with atoi failed since an uninitialized ctype table was used. This could also happen with any compiler, depends only of the order of objects in the libnix libs...

works as expected now. Thanks!
