[php-src] Issue #8393: Can't understand mount point directories on Windows

Issue: https://github.com/php/php-src/issues/8393 Comment Author: ggets **R:** is just a regular DOS Device mount point, mounted via registry like so: `Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\DOS Devices] "R:"="\\??\\C:\\bin\\mapdrive" ` From what I tested it is not the culprit of the problem as the reparsePoint behaved similarly in a regular folder. I should mention that **R:\dreamflame.in** is a rclone mount. Output of fsutil reparsePoint query R:\dreamflame.in: `Reparse Tag Value : 0xa0000003 Tag value: Microsoft Tag value: Name Surrogate Tag value: Mount Point Substitue Name offset: 0 Substitue Name length: 106 Print Name offset: 108 Print Name Length: 106 Substitute Name: \Device\Volume{a9035697-be97-11ec-8a2b-4851c5094231}\ Print Name: \Device\Volume{a9035697-be97-11ec-8a2b-4851c5094231}\ Reparse Data Length: 0xe0 Reparse Data: 0000: 00 00 6a 00 6c 00 6a 00 5c 00 44 00 65 00 76 00 ..j.l.j.\.D.e.v. 0010: 69 00 63 00 65 00 5c 00 56 00 6f 00 6c 00 75 00 i.c.e.\.V.o.l.u. 0020: 6d 00 65 00 7b 00 61 00 39 00 30 00 33 00 35 00 m.e.{.a.9.0.3.5. 0030: 36 00 39 00 37 00 2d 00 62 00 65 00 39 00 37 00 6.9.7.-.b.e.9.7. 0040: 2d 00 31 00 31 00 65 00 63 00 2d 00 38 00 61 00 -.1.1.e.c.-.8.a. 0050: 32 00 62 00 2d 00 34 00 38 00 35 00 31 00 63 00 2.b.-.4.8.5.1.c. 0060: 35 00 30 00 39 00 34 00 32 00 33 00 31 00 7d 00 5.0.9.4.2.3.1.}. 0070: 5c 00 00 00 5c 00 44 00 65 00 76 00 69 00 63 00 \...\.D.e.v.i.c. 0080: 65 00 5c 00 56 00 6f 00 6c 00 75 00 6d 00 65 00 e.\.V.o.l.u.m.e. 0090: 7b 00 61 00 39 00 30 00 33 00 35 00 36 00 39 00 {.a.9.0.3.5.6.9. 00a0: 37 00 2d 00 62 00 65 00 39 00 37 00 2d 00 31 00 7.-.b.e.9.7.-.1. 00b0: 31 00 65 00 63 00 2d 00 38 00 61 00 32 00 62 00 1.e.c.-.8.a.2.b. 00c0: 2d 00 34 00 38 00 35 00 31 00 63 00 35 00 30 00 -.4.8.5.1.c.5.0. 00d0: 39 00 34 00 32 00 33 00 31 00 7d 00 5c 00 00 00 9.4.2.3.1.}.\...`
