I think the error is a valid error. For comparison, NAG f95 5.1 shows the
following error message:
Error: line 19: Dummy proc DERIV arg 1 has different INTENT from actual proc
LOGISTIC4 arg
Error: line 19: Incompatib

Thanks for the update. I finally feel as though this is getting some teeth. I
don't know what the default behavior of the 4.3.2 compiler is, however the
command line that I used to invoke this behavior excluded any bit

Indeed.

It surely is, since the interfaces of your subroutines '

Registers also need to be consecutive, starting from certain register, i.e.:
str
When I compile the following code with gcc 4.4 and -O I get a lot of header
related errors. This doesn't happen without -O or with gcc 4.3.
Is this error expected, and if so, is there any way to improve the output from
gcc to make it clearer what's going on?

Putting a standard header inside a namespace is undefined.

Wouldn't it be easy to implement catalogs using a vector? If do_open adds the
catalog name to the vector and returns the index, do_get can get the name back
by using the catalog as the index into the vector.

I need to walk the stack from within an asynchronous signal handler, and every
once in a while, the program crashes in uw_frame_state_for. I know that
unwinding through a signal handler is 'discouraged', and that proper unwinding
information may not always be there, but the unwinder should fail gra

Wrong quote - and wrong statement. It is not a F2003 change, but already in

I thought of that, but using a vector will not be thread safe. Although I
don't believe that the C++ standard requires thread safety for std::messages,
applications will definitely expect thread safety here. The unde
