`make help` prints a weird line `Guestagents are unzipped each time to check the build configuration; they may be gunzipped afterward.`

[AkihiroSuda]

$ make help
Guestagents are unzipped each time to check the build configuration; they may be gunzipped afterward.
  binaries        - Build all binaries
  manpages        - Build manual pages

  help-variables  - Show Makefile variables
  help-targets    - Show additional Makefile targets

Not a very recent regression. Happens on both v1.2.1 and master.

It should only need to do this, when actually running the gunzip. Also there is a typo: unzip + gunzip ?

[afbjorklund]

ifeq ($(CONFIG_GUESTAGENT_COMPRESS),y)
$(info Guestagents are unzipped each time to check the build configuration; they may be gunzipped afterward.)
gz=.gz
endif

"they may be zipped afterward."

but might as well remove this output?

# returns the file name without .gz extension. It also gunzips the file with .gz extension if exists.
# $(1): target file
gunzip_if_exists = $(shell f=$(1); f=$${f%.gz}; test -f "$${f}.gz" && (set -x; gunzip -f "$${f}.gz") ; echo "$${f}")

# call force_build with passing output of gunzip_if_exists as an argument.
# $(1): target file
force_build_with_gunzip = $(call force_build,$(call gunzip_if_exists,$(1)))

this is where the info should be printed

$(LINUX_GUESTAGENT_PATH_COMMON)%.gz: $(LINUX_GUESTAGENT_PATH_COMMON)% $$(call force_build_with_gunzip,$$@)
        @set -x; gzip $<

maybe here as well, to match the gunzip
