Enable AC_SYS_LARGEFILE to set the macros needed for large file APIs to
be used by default. We do not want to define those macros in the
public headers that users include. The values of the macros are copied
to a separate file that is only included by the filesystem sources
during the build, and then the macros in <bits/c++config.h> are renamed
so that they don't have any effect in user code including our headers.
Also use larger type for result of filesystem::file_size to avoid
truncation of large values on 32-bit systems (PR 91947).

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])

# 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.
