A combination of the following steps should work.

a) Detect that configure is running under MSYS:

$ uname -a
MINGW32_NT-6.2 MYPC 1.0.18(0.48/3/2) 2012-11-21 22:34 i686 Msys
                                                           ^^^^
Perhaps there is already something in autotools for this.

b) Detect that the compiler is MinGW. There is an msys-gcc, but
the programs built by it can find `/bin/m4.exe', so there would
be no need to change it, although MSYS also understands
`c:/mingw/msys/1.0/bin/m4.exe', so it probably would not hurt.

The configure script already knows that the build system type
is i686-pc-mingw32. That should be good enough.

c) If you are running under MSYS, the command `pwd -W' gives you
the Windows path corresponding to your current directory, so:
$ echo `cd /bin;pwd -W`
C:/MinGW/msys/1.0/bin

Your current directory does not change.

I cannot reproduce the problem.  When I failed the first time, I copied 
doc/figs
from the git repository and tried again, but it told me that I did not 
have `dot'.
When I saw your message, I deleted doc/figs and extracted it again from 
the xz
archive. Strangely, it worked this time.
