(svn r26972) [1.4] -Backport from trunk:

- Fix: Compilation of strgen on various platforms like Solaris (r26850)
- Fix: Better display of refit information for articulated vehicles [FS#6113] (r26849, r26848)
- Fix: Do not assign a next hop when returning cargo [FS#6110] (r26847)
- Fix: The ok-button in the OSK for the signs list should just close the OSK [FS#6116] (r26827)
