I am trying to malloc a pointer to a file.  that should not be illegal 
but the messages are confusing.   if I just stick the malloc in the 
pointer I get OTHER ERRORS.


when I use that  ptr  I get   this

  (FILE *) prt =  fopen(....)

  lvalue casts are deprecated.
if i delete the (FILE *)  i get   pointer conversion to int without a  
cast,

  here I am trying to open a file.

are you sure this error condition is not a bug.  I cant find any 
configuration to remove the warnings.
