[e-users] (e16) undefined macro: AC_USE_SYSTEM_EXTENSIONS

[Yasufumi H. <yas...@ni...>]

Hi all

When I run configure to build e16 which I've checked out from cvs just now,
the script says:
    configure.in:28: error: possibly undefined macro: AC_USE_SYSTEM_EXTENSIONS
I found that this macro was introduced in autoconf 2.60, but the one on my
box is 2.59. Are there any workarounds for it?
Thanks in advance.
