Hi,

I believe there is a bug in the function func_convert_core_msys_to_w32,
as "cmd //c" opens a command prompt and then hangs on Windows 7,
preventing the caller from going any further, whereas if you change this
to "cmd /C", it works as intended. Not sure if older windows systems
worked with //c, but Win7 definitely doesn't.

Hope this helps,
Alex Franchuk

We're missing context. "cmd //c" is intended to be executed from MSYS
(function named ...msys_to_w32 remember) and the MSYS command line
parsing heuristic is supposed treat //c as if you really wanted to say /c.

And that works for me on Windows 7:

$ cmd //c type 'C:\MinGW\msys\1.0\bin\cmd'
#!/bin/sh

"$COMSPEC" "$@"
$ uname -s
MINGW32_NT-6.1


So, I'm wondering in what context your func_convert_core_msys_to_w32 is
running?

Cheers,
Peter
