[Lapack] integer size in f2c.h

I have come across a problem in the f2c.h header in
If the operating system is a 64-bit-integer version, as more and more
Linux systems are, the 'int' in C are 64-bit integers, not 32-bit
integers as they used to be. So the typedef declaration of 
typdef long int integer;
should be replaced by
typdef int integer;
by using some sort of common preprocessor flag (like checking __LP64__ )
to ensure that Fortran's 32 bit integers are still 32 bit on the C side.
