[PATCH] Use proper print formatter in main function in fixincl.c

[Nicholas Krause]

This fixes the bug id, 71176 to use the proper known
code print formatter type, %lu for size_t rather than
%d which is considered best pratice for print statements.

This is still changing the wrong format specifier (the one corresponding 
to apply_ct, which is an int).

Sorry for the dumb mistakes as I seem to have miscounted the variables over
in my understanding of the code.

I will resend again and sorry for wasting your time Joseph,

That was added in C99 and so is not part of C++98. GCC only requires a
C++98 compiler (and library).

Wouldn't the right fix be to not cast to unsigned long and use %zu?

Well the proper specifier for size_t is %zu, but since you cast to
unsigned long then %lu is right.

I'd expect "unsigned long" not "unsigned int long".

Re: [PATCH] Use proper print formatter in main function in fixincl.c

[Joseph Myers]

This patch is wrong for multiple reasons (the %d you're changing is for an 
int argument, so is correct as-is, and %lu is not portable for size_t, so 
since we may not be able to assume C99 %zu on the host you'd need to cast 
the ttl_data_size argument explicitly to unsigned long int to use %lu for 
it).
