This is some very old private code (from the mid-80ies, pre ANSI-

supposed to compile under Windows 3.x (!) with MSVisualStudio 4.
I have no clue what the compiler tries to tell me:
auto unsigned long lcl_l_flags = 0;
[snip]
But I *do* init the variable! So still the question is open: what
could be wrong with this code fragment? I know, warnings are not
errors - and sometimes the compiler is just plain wrong and the
code is OK. I am just curious as to why the compiler thinks there
might be problems.
So you do. I overlooked that detail. We can safely ignore my
previous comments, then.
I don't see anything obvious, but I have managed to confuse the
compiler with sufficiently twisty code before. I would try two things:
1) Preprocess the file (gcc -E; then edit the resulting file and
comment out all the #line's produced), and then compile the result.
See if you still get the error, and if the error still refers to that
line.
2) Comment out the macro, and put a simpler version of the expanded
macro in its place, e.g.,
if (spgfp == 0) ....
One of those two approaches may get you closer to the answer.
Sorry for the misdirection.
Regards,
Justin
