I saw this in the MinGW Users Digest today:

FWIW, you should also note that Woe32's own `exec' function, as provided by MSVCRT, is critically broken wrt the quoting of grouped arguments with included white space, which are present in the passed argument vector. The disfunctional `spawn' functions, which MSVCRT provides instead of the `fork()...exec()' API is identically broken.

For an explanation, and GPLed workaround, see:

I don't know if it is relevant for DOSBox??
