Subject: Duplicate use of symbol 'base_name'.

Some source files in the directory 'src/' are using a string variable
'base_name'.  At the same time the directory 'gnu/' uses the very same
identifier as a function.  It is expected that the linker will cause
some indeterminism in choosing which of these references to prefer at
linking time.  To avoid this randomness, the string variable is renamed.

Observe that 'src/rlopt.h' and 'src/rwopt.h' are generated by upstream's
release process from 'src/rlopt.opt' and 'src/rwopt.opt', respectively.
All of them are patched for better consistency.
