cygstart was contributed by Michael Schapp, who is still around but
doesn't post often. cygstart, aside from its option handling, is a very
simple app. The core routine just uses the Windows 'ShellExecute'
function on the specified file. Windows is then responsible for looking
up the associated application in the registry, starting it, and causing
it to load the specified file. I don't see how anything in cygwin
itself can affect that.
The ONLY thing I can think of is changes in path handing (conversion
between 'unix' and 'windows') as cygstart tries to prepare the target
file's pathname for passing into the ShellExecute function -- variable
name 'aPath' in the code below.
But I'll defer to Michael for futher analysis.

int ret;
setup_win_environ();
ret = (int) ShellExecute(NULL, action, aPath, args, workDir, show);
if (ret >= 32) {
return TRUE;
} else {
printf("Unable to start '%s': %s\n", aPath, startError(ret));
return FALSE;
}
}
