#7 Minor correction to Mac OS X compilation

[R. Mattes]

SYMPTOM:

An attempt to compile framerd on Mac OS X (ver. 10.2)
failed due to a missing link instruction. The linker
reports
'_gettext' and '_textdomain' as missing symptoms.

QUICK FIX:

add '-lintl' to the LDFLAGS in the toplevel 'makefile'.
Note: 'makefile' will be overwritten by 'configure'.

FIX:

Probalbly this should be fixed with 'automake/configure'
magic. I'll have a look at it.
