Unambiguously, the path separator for msys is ':'.  Epstopdf's test for msys is 
just from the value of the Perl variable $^O.  When the perl interpreter is the 
msys one, perl sets $^O to 'msys' and it uses ':' for the path separator.  When 
the perl interpreter is a native Windows one, it sets $^O to 'MSWin32', and the 
path separator is ';'.

That's independent of whether the perl in question is invoked from cmd.exe or 
from msys's bash.  (I've tried it all 4 ways.)
