Automake has its own conditional, which, unfortunately, share keywords
with GNU make conditionals. If you can convert your checks above to
automake conditionals, that would be good.
In configure.in, do
AM_CONDITIONAL(COMPILER_IS_COMPAQ_CXX, [test x"$CXX" = xcxx])
and in Makefile.am, do
if COMPILER_IS_COMPAQ_CXX
foo
else
bar
endif
Otherwise, in case of extreme duress, try this (untested):
In configure.in,
MK=''; AC_SUBST(MK)
And in Makefile.am:
@MK@ifeq ...
foo
@MK@else
bar
@MK@endif
However, you cannot put in automake magic variables (things like
foo_SOURCES, foo_LDFLAGS, etc) inside an ifeq/else/endif. Rather, you
can, but automake will get extremely confused if you do ;-)
