Multiply exported Gnulib symbols

[Ludovic Courtès]

Hi,

The following issue was brought up recently on the Guile list [0].

Suppose some library uses, e.g., the `strcasecmp' module, which exports
`strcasecmp ()' (assuming the module is actually compiled).  Suppose,
for instance, that an application using said library is also linked
against `strcasecmp'.  Then we may have troubles (depending on how the
application is linked to the library, depending on the OS, depending on
the dynamic linker's options, etc.).

Did you consider such situations already?  Any magic recipes to void
them?  :-)

Thanks,
Ludovic.
