LD_PRELOAD by itself only works with Cygwin builtin functions, but
|
|
textdomain() and friends come from libintl. In order to override
|
|
those functions, we have to "replace" cygintl-?.dll since functions are
|
|
bound to a DLL name at link time. Our replacement will be used since
|
|
it is loaded first by LD_PRELOAD.
|
|
|
|
But as we are making this *the* libintl, we need to provide
|
|
pass-throughs for the other functions which we're not overriding,
|
|
otherwise Locale::gettext won't load (not to mention the program
|
|
that we're trying to help2man).
