Thanks Graeme, I've been looking for a decent version of qltools for
some time to use on Linux.
David - if you are interested - the reason that qltools.c won't compile
without warnings on Linux is because the original code used various
typdefs from stdint.h, which, for example, defines the following:
typedef unsigned int uint32_t;
So, the unit32_t assumes that an unsigned int is 32 bits.
The C99 standard introduced those as actual types so that a uint32_t is
always guaranteed (!) to be 32 bits. In order to printf() those, this
now gives a warning:
printf ("Updates : %ld\n", swaplong (b0->q5a_mupd));
simply because the "%ld" is the format specifier for a long int and not
for a uint32_t. In order to get rid of the warnings, you need to either:
#include <inttypes.h>
...
printf ("Updates : %" PRIu32 "\n", swaplong (b0->q5a_mupd));
or, simply change the "%ld" specifier to "%u" for a simple unsigned int.
I think the later/latest versions of gcc defaults to c99, hence all the
warnings.
I'm in the middle of going through one of my old programs on Linux to
replace all the "%lu" etc with the appropriate c99 specifiers rather
than just making them all "%u". It should then be future proof! Famous
last words.

Cheers,
Norm.
