# Workaround for GNU make 3.80: it fail on 'eval' within 'if'
# directive after some level of complexity, i.e. after complex
# rules it fails on code:

# $(eval $(call do_so_links,cc,))
# $(eval $(call do_so_links,cc,_DBG))
# ifndef WITHOUT_STLPORT
# $(eval $(call do_so_links,cc,_STLDBG))
# endif
#
# Put 'if' logic into defined macro looks as workaround.
#
# The GNU make 3.81 free from this problem, but it new...
