[svn-r1979] Purpose:
Feature "improvement".
Problem:
The Makefile target triggers gmake to redo the whole auto-configure
process if it sees any autoconfigure related files changed. It causes
couple problems. One is that when multiple machines using --srcdir
are running make, they may detect the changes and launch the autoconf
at the same time. These end up as multiple hosts updating the same
srcdir area together--bad things can happen. Another one is that
when one modifies some Makefile.in, then try "make distclean" before
launching the configure process. Instead of cleaning things, it
started a configure, recreate all Makefiles and other files, then
finally come around to do the distclean--who knows what it cleans
by now since the Makefile is changed too. Last problem was that
this auto-process will launch even for command "gmake -n ...".
Solution:
Renamed Makefile target to reconfigure so that the auto-checking
is still available but must be launched explicitedly. If one
wishes to have the auto-checking as default, one may do
alias gmake "\gmake -i reconfigure; gmake \!* ".
