And on that note, would the proj maintainers accept a patch that adds a 
third parameter to dmstor(), an int* that when set to a non-NULL value 
will be an out parameter that is set to 0, 1 or 2 if the value read has 
no axis hint, is a longitude (eEwW postfix sign), or is a latitude (nNsS 
postfix sign) respectively?

What would be your preferred behaviour for the geod tool? I don't think 
changing the default order to match proj's output would be good, because 
it would break existing software that puts latitude before longitude. So 
I would only add a check to see if the postfix sign indicators suggest 
that the first argument is a longitude, and just silently swap them so 
that you get the correct result.

Alternatively, an error or warning could be generated instead of 
silently giving the correct answer, but I don't see the added value in that.

Finally, do I send a patch to the mailing list or do you prefer a git 
pull request?
