I have only the branch for version 8.0. I upgraded my autoconf (it is weird if autoconf 2.13 is the source of the problem!) and now the error with VPATH is gone, but at the end, compilation fails and no executable is generated. I have attached the log file of my compilation. My branch is also up-to-date. I have run "git pull" before and "git fetch" continuously. Any help will be appreciated. I also got the following warnings which seem not to be a big deal:
config.status: WARNING: '/home/danesh/pike/src/Makefile.in' seems to ignore the --datarootdir setting
configure: WARNING: No Login-related functions, username and password will be silently ignored
configure: WARNING: Outdated postgresql version, using potentially unsafe string escaping function
configure: WARNING: gtk/gtk.h: accepted by the compiler, rejected by the preprocessor!
configure: WARNING: gtk/gtk.h: proceeding with the compiler's result
