It matters from a debugging perspective. The symbols store the struct name,
not the typedef.
Anyone expecting to dump data based on the data type with an underscore
would get an error on reactos.

I've just had a look at win7:

Symbol ntdll!RTL_DRIVE_LETTER_CURDIR not found.
0: kd> dt ntdll!_RTL_DRIVE_LETTER_CURDIR
   +0x000 Flags            : Uint2B
   +0x002 Length           : Uint2B
   +0x004 TimeStamp        : Uint4B
   +0x008 DosPath          : _STRING

So we actually break compatibility with Windows by not copying struct names
This is indeed a typo that needs fixing.
