It's ugly, but I can live with that since it's the only location
which needs this special kind of attention.
Umm. I must agree - as a workaround for 1 problematic line, the 7 +
3 line insertion is too much. Can I replace the insertion by some C
preprocessor macro (and expand it by
Dear Garrick,
Thank you for remembering your experience and posting it.
As you wrote, I'm questionable how many die-hard CW for
Mac users are writing new softwares. But I found that
same issue is found in the latest CW for embedded platform
that defines jmp_buf as an array of long pointers.
Dear Antoine,

So, now I have 3 workarounds:
Did you try
jmp_buf volatile* dest = ( a_struct_ptr-jb_memb );
If this works, you've got a 4th workaround: there is no difference for a
conforming compiler between the two
So, the implicit cast issue is not exceptional error in CW for
MacOS/ColdFire. Thus, I want to insert CW-specific pragma as
following. [...]

Wow, you've done a great and detailled analysis.
Thinking about a code like:
struct a_struct_ {
jmp_buf jb_memb;
} volatile* a_struct_ptr;
volatile jmp_buf* dest = ( a_struct_ptr-jb_memb );
...
For volatile jmp_buf* dest, according to the error message
