A target_os conditionally applied -lfoo switch

[Earnie Boyd]

I need to add a library specific to a target_os.  I've tried several 
possible techniques and can't get cooperation from the tools.

What I want is something similar to:

target_os := @target_os@

ifeq ($(target_os),mingw32)
  LDADD += -lws2_32
endif


Unfortunately automake thinks the conditional belongs to it instead of make.

Help?

Earnie.
