Subject: [PATCH, Modula2] PR-108142 Many empty directories created in the build directory
Date: Tue, 10 Jan 2023 01:48:29 +0000	[thread overview]
Message-ID: <87h6wzf9ci.fsf@debian> (raw)


PR-108142 Modula-2 configure generates many subdirectories in the top
build directory.  This patch dynamically creates subdirectories under
gcc/m2 if and when required.

Bootstrapped on x86_64 gnu/linux, ok for master?

regards,
Gaius
