Unless a file has a *.pro or *.sav extension, IDL cannot
"find" it automatically. The person who wrote the *.h file
for IDL had been to too many C programming workshops. :-)

The proper way to write a file with structure declarations
is to give the file the "name" of the structure with __DEFINE.PRO
(two underscores) appended to it. Put this file in the !PATH 
and IDL will find it automatically when you create the structure
in the code.
