Right, because the implementation of a replacement snprintf in MinGW is
relatively new.  Prior to that the system snprintf was used.

I don't understand why you need this environment variable set at all. 
The compiler is relocatable and should be able to find its libraries
relative to its installation location without any help.  Maybe the
relocation code in g95 doesn't work and they need this crutch of
LIBRARY_PATH, but I would certainly try just getting rid of it entirely.
