I've modified the MinGW runtime such that the GCC specs file is
incorrect with regard to the oldname library and you've used an old
name. You have three options:
1) Don't use the oldname function, i.e.: use the _stat() version
instead.
2) gcc -o stat stat.c -lcoldname
3) Apply the attached patch:
A) download diff file to /tmp/specs.diff.txt
B) cd /
C) patch -i /tmp/specs.diff.txt
Cheers,
