@adrian-prantl, I'll be glad to help:)
dwarf on Win has warnings like `objdump: Warning: DW_FORM_line_strp offset too big: 0x4008a16c` and no inlined source
here is a part of `$ objdump --dwarf a.out` ([full](https://github.com/amordo/TestInlineSourceFiles.test_dwarf/blob/main/objdump_win_out.md))
```
The File Name Table (offset 0xaf, lines 2, columns 3):
Entry Dir (Unknown format content type 8193) Name
0 0objdump: Warning: DW_FORM_line_strp offset too big: 0x4008a161
(indirect line string, offset: 0x4008a161): <offset is too big>objdump: Warning: DW_FORM_line_strp offset too big: 0x4008a14f

while linux has one

1 1 (indirect line string, offset: 0x106): void stop();
void f() {
// This is inline source code.
stop(); // break here
}
```
you can look at Win test result there (+ added 2 .md with the objdump outputs)

ps. played replacing '/' on '\\' in paths in `inline.ll`, no effect
