So I ened up doing both:
1) add missing tiny wrappers to distrib/utils/libhack untill the main
locale references to libc disappeared (that is most of the multibyte
locale code got not pulled in any more)
2) create a makefile hack to build libcurses and nvi w/o WCHAR support
The resulting "instbin" sizes (the crunched and stripped binary containing
all userland code on the media) was:
Method 1 Method 2 diff
atari install floppy 1326224 1309808 16416
sun3 miniroot 1878976 1811280 67696
I consider the additional gain worth the hackish makefiles and will commit
both (as part 1 will also help other install media).
For the archives: the method I used to find symbols missing was: start with
uwe's list (some symbols were already covered) and then add
LDADD+= -Wl,-Map=instbin.map
to the generated instbin.mk file in the object directory. Looking at the
map file it became obvious which symbol references caused inclusion of things
like is_multibyte.o from libc. I then iteratively added those to libhack
and rebuild, untill no linker failures occured and the whole thing was
small enough (i.e. the build did not fail).
