Example below similar to Kernihan & Ritchie [1978], p 124.
Gives error 69 using SDCC.

struct {
int a;
int b;
} astruc[] = {
1, 1,
2, 2
};

void main(void)
{
}

    SDCC output:
    init.c:4: error 69: struct/union/array 'astruc'
    :initialization needs curly braces

    This is perfectly fine for me -- add curly braces around
    each struct initializer and you are done.
    I guess your code is non-valid ANSI C code (according do a
    draft of the standard, struct and union initializers must be
    brace-enclosed (6.7.8:16)).

    Can anyone confirm this?

    Fixed code:
    struct {
    int a;
    int b;
    } astruc[] = {
    {1, 1},
    {2, 2}
    };

    void main(void)
    {
    }

    I've always kept my old copy of K&R as my C reference
    standard. However, if it compiles (confirmed) with extra
    braces (whether standard or not) I'm happy. Thanks for the
    quick turn-around.

    Jim,

    Allthough I don't have my copy of C99 at hand right now, I
    know SDCC does not support initialization without the extra
    braces. Using them however makes so much clearer code
    and it definitely is according to the standard.

    And there are more things in K&R that SDCC does not
    support, like:
    foo()
    int a;
    {...}
    to declare parameter a.

    I don't think we have any intention on changing that.
    Greets,
    Maarten
