no. Take a look at src/Makefile.inc:

# libcurl has sources that provide functions named curlx_* that aren't
part of
# the official API, but we re-use the code here to avoid duplication.
CURLX_ONES = \
        ../lib/strtoofft.c \
        ../lib/strdup.c \
        ../lib/rawstr.c \
        ../lib/nonblock.c

so that means that you have to include these sources directly (as other
platforms do too)...

Gün.
