[ADMB Users] Changes in getting/not getting an std file between Versions 9 and 10

[Weihai Liu]

I run both ADMB version 9 and 10 on MinGW compiler on windows, your example
in list (2)  can not create .std file on both version and both complain.
also your examples in list(5) both worked on the two version, which they
should. So I guess it may due to the different compiler, you are using
borland. The other thing is you may have to delete the .std file before you
run the test, or at least check the time stamp of the file.
