GRFcodec problems

[weeknie]

Wasn't sure where to put this so I put it here, sorry if it's in the wrong place

Anyway, I've been trying to set my minGW/msys up with grfcodec, but the compiled exe seems to be broken.
Every time I do anything (for example "grfcodec -d dutchtrainsw.grf"), all it does is display the help text.

I also tried compiling grfcodec myself from sources (again under minGW/msys), but then I get the following error:

grfcodec.cc: In function `int decode(const char*, const char*, const U8*, int, int, int, int*, int)':
C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/io.h:302: error: too many arguments to function `int mkdir(const char*)'
grfcodec.cc:549: error: at this point in file

If I make my way around that by removing the excess argument, it gives this error, which I can't work around:

grfcomm.c: In function `char* spritefilename(const char*, const char*, const char*, int, const char*, int)':
grfcomm.c:137: error: `mkdir' was not declared in this scope
grfcomm.c:137: warning: unused variable 'mkdir'

mkdir should exist in that scope (or better to say, I don't see why not), but well

Does anyone have any ideas how I could fix this and get grfcodec working on my minGW/msys install?

Thanks in advance

EDIT: these problems occur with the HEAD, 2125 and 819 revisions

2nd EDIT: forgot to metion that I'm running this on a 64 bit windows 7 machine. After some googling I noticed there were some specific problems with 64 bit 7, but non of the proposed solutions helped

Ok, it seems fixed, but I'm not sure what fixed it, I'll edit this post when I found out

EDIT: the fix is putting the exe's in the minGW bin folder (for me C:/minGW/bin), instead of the msys folder (C:/msys/1.0/bin for me)

Sorry for the useless post
