GDB and MacOS 11.4/BigSur

[Sam Warner]

Hi Simon,
   Thank you - the added details you gave me really helped, especially when I both obtained the official 10.2 source set, and followed the BuildingForDarwin <https://sourceware.org/gdb/wiki/BuildingOnDarwin> instructions for  ".configure --disable-intl”.

  I successfully built now, and off to use the test-suites

The build is still progressing at this moment.  Which is a significantly longer duration than before.
