I tried configuring m4 with its --enable-debug switch, which enables various -W
warning options, and combined it with -Werror to forcefully see the warnings.
The compilation choked when compiling libltdl. The check for AC_C_CONST is now
obsolete, but warned due to -Wshadow, which made it fail

A followon - using LTDL_SET_PRELOADED_SYMBOLS() choked with -Wnested-externs.
