this works:

creating gettext

witten src# 

ie. use CPP from gcc and then compile the resulting C code with clang and call
libtool (which uses clang for linking) to link it all

this does NOT work:

witten src# clang -E -DLOCALEDIR=\"/usr/local/share/locale\" -DHAVE_CONFIG_H
-I. -I.. -I. -I. -I.. -I../intl -I./../intl -I../gnulib-lib -I./../gnulib-lib

-DMALLOC_PRODUCTION -march=native -fno-strict-aliasing -c gettext.c >
/tmp/gettext.c  clang: warning: argument unused during compilation: '-c'

witten src# cp /tmp/gettext.c .

witten src# clang -c gettext.c -o gettext-gettext.o

clang: error: linker command failed with exit code 1 (use -v to see invocation)

witten src# 

ie. exactly the same steps as before except that I used clang's cpp. when I try
to use gcc to compile the clang's CPP produced C code it emits:

witten src# gcc -c gettext.c -o gettext-gettext.o      
line-map.c: file "gettext.c" left but not entered

I dont know what I should provide for you to fix this but feel free to ask I
can provide whatever you want
