checking for working mmap... no

[andrewbachmann]

While trying to configure a gcc build I noticed configure said:

"checking for working mmap... no"

I extracted the test program from the configure script and it fails in a malloc. I have added printfs to the program so as to make it more descriptive. The error printed is: "data3 null". The failing line is: data3 = (char *) malloc (pagesize);

To compile this program, simply: gcc mman.c -o mman And run ./mman

I am running revision 34251, gcc2hybrid. The program fails if I compile it with gcc2.95.3-haiku-090629 or if I compile it with gcc 4.4.2 (from joe protsko).
