Shouldn't all of the above removed by now, with 07bbe4ca (Merge
branch 'jc/make-libpath-template', 2024-02-06) that merged the
support for platforms whose linker does not have a way to specify
the path used at runtime to locate dynamic libraries and is already
in the Git 2.44 release?  The autoconf-generated config.mak.autogen
would leave CC_LD_DYNPATH to empty on such a platform, which then
adds only one "-L $where" (instead of the usual "-L $where -R
$where") on the linker command line, making your earlier workaround
to use "-L $where -L $where" unnecessary?

"Introduce z/OS ..." (cf. Documentation/SubmittingPatches)

Or perhaps

	Add platform specific settings in config.mak.uname for zOS
	(OS/390).

All of the above should be indented with TAB to imitate the support
for other platforms, I think.

Thanks.
