Double '$' in jdk/make/RunTests.gmk

Wed Mar 15 11:27:02 UTC 2023

Hi, I noticed a double usage  of ‘$’  in

jdk/make/RunTests.gmk

800   ifeq ($$(call isTargetOs, windows), true)
801     $1_JTREG_BASIC_OPTIONS += -e:_NT_SYMBOL_PATH

Is there some good  reason for this,  the other  call isTargetOs   - snippets in the Makefiles do not use $$    ?

Best regards, Matthias
