Why did this ever work? Hard to say...perhaps a library we linked against was setting `int _dowildcard = -1;` somewhere and no longer is. Apparently linking with CRT_glob.o has been the way to do this for a very long time, and we've just been lucky that it worked all this time.

// non-Windows, globbing is done by the shell, so passing '*'
|
|
// shows up as '*'. In Windows, it is necessary to link a certain
|
|
// way for this to work. To test this, we invoke this program with
|
|
// a single quoted argument containing a shell glob expression. In
|
|
// Windows, we expect to see multiple arguments, none of which
|
|
// contain '*'. Otherwise, we expected to see the exact glob
|
|
// string that was passed in. The effectiveness of this test was
|
|
// exercised by manually breaking the link options for msvc and
|
|
// seeing that the test fails under that condition. Explicit link
|
|
// changes used to be needed only for MSVC, but as of late 2024,
|
|
// they are also neededed for mingw, which was found by CI failure
|
|
// of this test.
