Both windows show the same make problem:

gawk: cmd. line:1: error: ? * + or {interval} not preceded by valid subpattern: /??_7.*@@6B@/
make[3]: *** [lib/JvmMapfile.gmk:116: /d/a/jdk17u-dev/jdk17u-dev/build/windows-x64/hotspot/variant-server/libjvm/symbols-objects] Error 1
make[3]: *** Deleting file '/d/a/jdk17u-dev/jdk17u-dev/build/windows-x64/hotspot/variant-server/libjvm/symbols-objects'

Which I see also with the underlying change.
Strange, I can't see how the changes can cause this error.
Is this a problem of the windows/cygwin gawk?
