#3268 Backslash in target path using -MD

[MMA]

SDCC version 4.1.0

Running sdcc with -MD flag and setting a folder as output:
sdcc -ooutput/ -IC:\test\ -MD -c ./main/main.c
Will result in a dependency file (output\main.d) having a backslash in the target name, making it unusable with make:
output\main.rel: main/main.c C:/test/main/main.h

Meanwhile running sdcc with output being a file:
sdcc -ooutput/main.rel -IC:\test\ -MD -c ./main/main.c
Produces a correct target name with a forward slash:
output/main.rel: main/main.c C:/test/main/main.h

Directory tree:

C:\TEST
├───main
│       main.c
│       main.h
│
└───output
        main.asm
        main.d
        main.lst
        main.rel
        main.sym

main.c

#include "main/main.h"

int main() 
{
    return 0;
}

main.h

// Empty
