dnl In autoconf 2.5x, AC_OUTPUT is replaced by four AC_CONFIG_* macros,

dnl which can all be called multiple times as needed, plus one (different)

dnl AC_OUTPUT macro. This one lists the files to be created:

AC_CONFIG_FILES(Makefile)

AC_CONFIG_FILES([scripts/testsuite_flags],[chmod +x scripts/testsuite_flags])
|

AC_CONFIG_FILES([scripts/extract_symvers],[chmod +x scripts/extract_symvers])

AC_CONFIG_FILES([doc/xsl/customization.xsl])

# Multilibs need MULTISUBDIR defined correctly in certain makefiles so
|
|
# that multilib installs will end up installed in the correct place.
|
|
# The testsuite needs it for multilib-aware ABI baseline files.
|
|
# To work around this not being passed down from config-ml.in ->
|
|
# srcdir/Makefile.am -> srcdir/{src,libsupc++,...}/Makefile.am, manually
|
|
# append it here. Only modify Makefiles that have just been created.
|
|
#
|
|
# Also, get rid of this simulated-VPATH thing that automake does.
