#3676 error using structs in macros

[Under4Mhz]

The following code fails to compile using sdcc, but succeeds with gcc:

/// GPL 2.0 or later
#include <stdio.h>
#include <stdint.h>
#include <stdbool.h>

void dotest(void) {}

typedef struct {

    uint8_t count;

} TestData;

TestData testData;

#define for8( var, size ) unsigned char var; for ( (var) = 0; (var) < (size); (var)++ )

void for1test(void) {

    for8(count,testData.count)
    {
        dotest();
    }
}

// sdcc -mz80 ./forbug.c -c

$ sdcc -mz80 ./forbug.c -c
./forbug.c:20: error 26: '' not a structure/union member

gcc ./forbug.c -c -Wall

sdcc -v
SDCC : z80/sm83/z80n/mos6502 TD- 4.3.6 #14442 (Linux)

[Philipp Klaus Krause]

This is unrelated to the macro: the issuecan be reproduced using this variant:

void dotest(void);

typedef struct {
    unsigned char count;
} TestData;

TestData testData;

void for1test(void) {
    unsigned char count;
    for (count = 0; count < testData.count; count++ )
        dotest();
}
