[bug #64806] "invalid output sync mutex" on windows

[Gergely Pinter]

Follow-up Comment #15, bug#64806 (group make):

Having placed a breakpoint on the error() function, it seems that the
"mingw32-make: *** [Makefile:7: cmp3] Error 130" error message comes from this
function call chain:

#0  error (flocp=flocp@entry=0x0, len=len@entry=40,
    fmt=fmt@entry=0x60982d "%s[%s: %s] Error %d%s%s") at src/output.c:450

However since this only happens after Ctrl-C-ing the hung process, I guess
this is not the root cause.
