and then at runtime, we hit an abort().

Since this field is really serving as the header to an arbitrary buffer,
using a flexible array instead should solve the issue.
What you want is ANYSIZE_ARRAY, which already exists.
i dont see how that would help.  the code is currently:
typedef struct ... {
        ...
        CHAR foo[1];
} ...;

it needs to be "foo[]".
Just a question to satisfy my curiousity:

Is this supported in C89 code? If not, then the char[1] has to remain because the code level is C89.

States to avoid C++, C99, and non-portable C constructs.
