Thanks for the quick reply.

Juding by config.log, there is an isinf implementation as a macro.

configure:44304: checking for macro isinf
configure:44322: mipsel-unknown-linux-uclibc-gcc -o conftest -Os 
inter -fno-builtin -Wall -Wstrict-prototypes -fno-omit-frame-pointer 
conftest.c -lm    >&5
conftest.c:131: warning: function declaration isn't a prototype
configure:44328: $? = 0
configure:44332: test -z
                          || test ! -s conftest.err
configure:44335: $? = 0
configure:44338: test -s conftest
configure:44341: $? = 0
configure:44353: result: yes

So I'm puzzled why it doesn't get picked up. Unfortunately, your 
build.log does not cover the building of libkaffevm, the library that 
references the missing symbols. Could you try to rebuild kaffe from 
scratch, i.e. in a new, pristine directory and send me the resulting 
build log? Please use

make CFLAGS="-H"

to build kaffe, as that will enable header file inclusion tracking, so 
that we can see if the header files containing the macros actually get 
included or not.

Maybe, but I'd doubt it. It seems like there is some small configuration 
problem, and I think we should be able to fix that together ;)
