The 'clean' target is still noticeably slow on cygwin, despite the
improvements made by previous patches. For example, the second
invocation of 'make clean' below:
$ make clean >/dev/null 2>&1
$ make clean
make -C git-gui clean
make: Entering directory '/home/ramsay/git/git-gui'
GITGUI_VERSION = 0.21.0.78.g38c2a
rm -rf git-gui lib/tclIndex po/*.msg
has been timed at 8.430s on my laptop (on old core i5-4200M @ 2.50GHz,
8GB RAM, 1TB HDD).
Notice that the Makefile, as part of processing the 'clean' target, is
updating the 'git-gui/GIT-VERSION-FILE' (not to be confused with the
similarly named file at the root directory of the repository). This is
to ensure that the $(GITGUI_VERSION) make variable is set, once that file
had been included. (The Makefile target uses the 'git-gui/GIT-VERSION-GEN'
script to generate that file, which should also not be confused with the
similarly named script at the root). However, the 'clean' target does not
use the $(GITGUI_VERSION) variable, so this is wasted effort.
In order to eliminate such wasted effort, use the value of the internal
$(MAKECMDGOALS) variable to only '-include GIT-VERSION-FILE' when the
target is not 'clean'. (This drops the time down to 6.454s, on my laptop,
giving an improvement of 23.44%).
