That is no longer + the case though, and has not been for quite a long time: the bug + is no longer present in the 5.6.2 version of perl and the 2.25 + version of Getopt::Long (and today, the latest versions of perl + and Getopt::Long are respectively 5.14.2 and 2.38). The obsolete + workaround for that Getopt::Long bug can thus be removed from our + 'getopt' function. + + It is also worth noting that such a workaround was quite buggy + and brittle itself; for example, a command like this: + "autom4te --output -" + would have caused the incorrect diagnostic: + "autom4te: option `--output' requires an argument" + Much worse, a command like this: + "autom4te --language=autoconf --output - configure.ac" + would have caused the standard input of autom4te to be processed + and copied into the 'configure.ac' file, deleting its pre-existing + content! Surely not what a user would have expected. + + After this change, a command like this: + autom4te --language=autoconf --output - - <configure.ac >out + works as expected, processing the input from 'configure.ac' and + writing it to the 'out' file. + + * lib/Autom4te/General.pm (use): Require perl version 5.6.2. + (getopt): Remove the old workaround. + +2012-01-15 Jim Meyering <meyering@redhat.com> + + avoid new warning about undefined $ARGV[0] + * lib/Autom4te/General.pm (getopt): Avoid warning induced by + yesterday's change: $ARGV[0] may not be defined, e.g., when + invoked via autoreconf. + +2011-01-14 Stefano Lattarini <stefano.lattarini@gmail.com> + + getopt: fix diagnostic for missing mandatory option argument + Before this change, an incorrect command line usage: + "autom4te --output" + triggered broken diagnostic like: + "autom4te: unrecognized option `--output'" + instead of the expected and correct: + "autom4te: option `--output' requires an argument" + * lib/Autom4te/General.pm (getopt): Give correct diagnostic in + case of usage errors due to missing arguments for options for + which they are mandatory.
