Re: [Dev-C++] can't compile dcraw.c

You did remember to compile without optimization? Adding debug information
but not turning off optimization makes for very interesting debugging,
since the compiler will rearrange the order of the generated code compared
to the order of the source lines.

Debugging an optimized binary is only meaningful in assemply mode, to look
for code code that isn't behaving correctly under optimization, i.e. that
is compiled with wrong flags (assumption of aliasing for example) or if
the compiler is suspected of generating incorrect (or bad) code.
