[PATCH 5/6] config.guess: replace POSIX $( ) with classic ` ` throughout |
|
Date: |
Sat, 22 May 2021 00:26:42 -0500 |
The previous replacement of backticks with POSIX command substitutions
was ill-considered and illogical: this script recognizes many archaic
machine types that probably never had POSIX shells, therefore it needs
to be able to run successfully under pre-POSIX shells.
Nor was there any significant difficulty in doing this reasonably, and
only a relative few terms needed to be factored into intermediate
variables to complete this change.
* config.guess: revert POSIX command substitutions to classic form
