Hello Alastair, I've managed to pinpoint the issue: in 1.6.0, the original Makefile defines a -D__64BIT__ which changes the meaning of g2int and g2uint from long to int. However, this is wrong on 64-bit Linux where int is still 32-bit, not 64-bit. The quick and dirty solution to this is to remove the -D__64BIT__ define from the makefile. The long-term solution would be to ask the libgrib2c developers to replace the conditional definition based on the __64BIT__ macro with an #include <stdint.h> and then typedef int64_t gint; typedef uint64_t g2uint, which is guaranteed to use the correct dimensions regardless of architecture (as long as the host compiler has a stdint.h, which it should have since they force gcc now).
