Subject: [PATCH] Spreadsheet: Fix trouble with clang and MacOS

Since the Spreadsheet: support cell binding commit, I got trouble by building freecad. I didn't find similar reports in install/compile forum. So I will only use the old version of typedef for macos. Better solutions are welcome.

See [trouble details](https://github.com/FreeCAD/FreeCAD/commit/68fca409833ca0c8c3811ad4efddcfcc3e2e4255#commitcomment-62364932)
