Hello; I am using bash and Fedora; I tried to remove a variable from a configure.in and after reconfiguration it seems to come back Here is an excerpt from configure.in: if test "$itcl_cv_prog_gcc" = "yes" ; then CFLAGS="$CFLAGS -fwritable-strings -Wshadow -Wtraditional -Wall" fi but after I remove if test "$itcl_cv_prog_gcc" = "yes" ; then CFLAGS="$CFLAGS -Wshadow -Wtraditional -Wall" fi and reconfigure it still shows the variable - from config.log: configure:3516: result: yes configure:3532: checking default compiler flags configure:3541: result: -fwritable-strings -Wshadow -Wtraditional -Wall How do I make sure it is cleared from the nested configure structure?
