No, it does not. These files were produced by mingw64. File considers them
data:
/home/austin/.wine/drive_c/windows/mono/mono-2.0/lib/mono/4.5/mscorlib.pdb:    
                                                                               
                                 data

whereas real .pdb files from visual studio appear as:
./memory/mozalloc/mozalloc.pdb:                   MSVC program database ver
7.00, 4096*95 bytes

it's produced by Mingw, not Microsoft. Whereas my real pdb's first line is:
Microsoft C/C++ MSF 7.00
DS

The first hex character is 0x4D, however (maybe I'm misunderstanding what
you're asking).

FYI, I uploaded the file here:
http://austinenglish.com/files/for_valgrind/mscorlib.pdb

the genuine pdb files I used are at
https://phoenixnap.dl.sourceforge.net/project/wine/Wine%20Gecko/2.36/wine_gecko-2.36-x86-dbg-msvc-pdb.tar.bz2

I'll get this in a bit or tomorrow.
