Ok, it works for this error but then still croaks a bit later:

libtool: compile:  gcc -pthread -DHAVE_CONFIG_H -I.. -I.. -I..
-I/opt/TWWfsw/libgmp41/include -I/usr/local/readline/include

numbers.c:5356: warning: incompatible implicit declaration of built-in
function 'sincos'
gmake[3]: *** [libguile_la-numbers.lo] Error 1



btw: I have in cppflags those flags:

-I/opt/TWWfsw/libgmp41/include -I/usr/local/readline/include
-I/usr/local/include

How come do they get duplicated?
And the -I.. also are showing up more than once...

Great! Thanks,
