I recognized a problem relating to the symbol __progname after downloading
the last cygwin (dll,lib,header) snapshot and linking a little app. At first
there was not problem. But after using the getopt_long function, linking was
okay, but on starting the app, the windows runtime loader say that cygwin1.dll
does not contain a symbol __progname.
If have looked in /lib/libcygwin.a to identify the relating object file and
found a reference to __progname, but I havn't found where this symbol is
defined. :-(
What me helped, was upgrading to the newest cygwin release (1.3.4-3)
