[...] The problem is that the size and some of the offsets of the C struct statfs computed by hsc2c are wrong: i'm in a 32bit linux system, and i've checked, using a C program, that sizeof(struct statfs) is 64 (hsc2 is giving 84 -- although perhaps Haskell needs additional space for housekeeping?), and that the offsets of f_bfree and f_bavail are, respectively, 12 and 16 (not 16 and 24). Also, i know that 12 and 16 are the right values because putting them by hand gives me the correct statfs values.
If you compile your C program with -D_FILE_OFFSET_BITS=64 you'll get the same numbers that hsc2hs does.
