I think I can manage to add an include before netinet/tcp.h

Fine. It seems compiler generate two names for a function, for instance 

         0 T .tds_free_bcp_column_data
...
     15224 D tds_free_bcp_column_data

as linux nm manual say T should be text while D should be data. I don't
know why data for a function but you can see that every "D" occupy 12
bytes (there is only an exception) while "T" occupation is not fixed so
I think "T" is really code. At this point the question is: why linking
shared library does  libtool remove symbols that start with dot ??

Could you issue a 

/usr/bin/nm -B -BCpg /usr/bin/nm | head 

just to check if an executable imports dot or not dot symbols??

Mmmm... what give 

grep TCP_NODELAY /usr/include/netinet/tcp.h

I looked deeper at your makes and I found a really weird thing... did
you run configure with different flags using
--disable/enable-shared/static? The output if VERY different !!! Just
look at the top

make1:

        if /bin/sh ../../libtool --tag=CC --mode=compile gcc

".deps/asprintf.Plo"; else rm -f ".deps/asprintf.Tpo"; exit 1; fi

-Wno-long-long -g -O2 -MT asprintf.lo -MD -MP -MF .deps/asprintf.Tpo -c
asprintf.c  -DPIC -o .libs/asprintf.o

make2:

        if /bin/sh ../../libtool --tag=CC --mode=compile gcc
-DHAVE_CONFIG_H  -I. -I. -I../../include -I../../include
-D_FREETDS_LIBRARY_SOURCE -DUNIXODBC -DHAVE_UNISTD_H -DHAVE_PWD_H

-c -o asprintf.lo asprintf.c;  then mv -f ".deps/asprintf.Tpo"
".deps/asprintf.Plo"; else rm -f ".deps/asprintf.Tpo"; exit 1; fi

-Wno-long-long -g -O2 -MT asprintf.lo -MD -MP -MF .deps/asprintf.Tpo -c
asprintf.c -o asprintf.o

one with PIC and one without, one asprintf.o and the other
.libs/asprintf.o (from the same libtool command!)

some lines below

make1:

ar cru .libs/libreplacements.a .libs/iconv.o .libs/asprintf.o
.libs/vasprintf.o .libs/readpassphrase.o .libs/strlcpy.o .libs/strlcat.o

make2:

ar cru .libs/libreplacements.a  asprintf.o vasprintf.o strlcpy.o
strlcat.o

now... you can understand why tsql failed to compile (in make2)..
readpassphrase.o was not included !!!
