There a at least three things that are strange here:
1. IAR doesn't seem to care that the recv() macro (defined at the
end of sockets.h) is a function-like macro but 'recv' is not used as
a function in tcp.c. That might be a problem of compiling it as C++
(and not C).
2. It seems like somehow tcp.c includes sockets.h (which it
shouldn't) - or where does the redefinition from 'recv' to
'lwip_recv' come from? Did you place an include to sockets.h
somewhere in a global header file (e.g. lwipopts.h or cc.h)?
3. tcp.c 837 of lwIP 1.3.2 says "pcb->flags &= ~(TF_ACK_DELAY
| TF_ACK_NOW);" - I don't see where recv or lwip_recv is
referenced??
If you don't find why sockets.h is included from these files, I'd
recommend to disable LWIP_COMPAT_SOCKETS first, that should correct
it, but you then have to define it to 1 in every application file
before including sockets.h (if you really need that feature).
Also, you might want to upgrade to 1.4.0, since 1.3.2 is outdated.

LOL, that's a funny footer for a message sent to a public list which
