Hi,
aclocal is stripping comment lines from configure.in, but not from
other files. Hence it can detect wrong dependencies and output useless
functions in aclocal.m4.
For instance the macro AC_PATH_GENERIC (from the autoconf
archive) refers to AM_PATH_GTK in its comments:
% grep m4/generic_path.m4 AM_PATH_GTK
dnl At present there is no support for additional "MODULES" (see AM_PATH_GTK)
Any use of AC_PATH_GENERIC will trigger the inclusion of AM_PATH_GTK:
% aclocal --verbose
[...]
saw macro AC_PATH_GENERIC
aclocal: configure.in: 226: macro `AM_PATH_GTK' not found in library
[...]
