 Running `autoconf -Wall' may show dubious or obsolete constructs.  They 
need not necesarrily be fixed immediately, but they are worth looking at.

 Also there's a bug in autoconf 2.59 that was still present in the head a
few days ago.  Under certain conditions macros that are pulled by
AC_REQUIRE are expanded too early, possibly leading to certain
initialization steps being executed after bits that depend on them.  
Finding them may be difficult, requiring a thorough study of the generated
script, or sometimes a strange error at the configuration time may be a
hint.  One example is expanding AC_CANONICAL_BUILD before
AC_CONFIG_AUX_DIR -- this leads to an attempt to use $ac_config_sub before
it's initialized.  I've filed a bug report -- no response yet.

 The bug shouldn't affect binutils -- I've been using autoconf 2.5x
(including 2.59) for all directories for some time now with no problems (a
few patches are needed, but not related to the bug).
