automake 1.11 parses if statement too late

[Bernhard Rosenkraenzer]

Hi,
this part of a Makefile.am causes errors with automake 1.11:

if IPHONE
# What ****ing ***** came up with the idea of a platform without shared
libraries???
lib_LIBRARIES = libtest.a
libtest_a_SOURCES = test.cpp
libtest_a_LDFLAGS = -lsomelib
else
lib_LTLIBRARIES = libtest.la
libtest_la_SOURCES = test.cpp
libtest_la_LDFLAGS = -lsomelib
endif

The errors are

Makefile.am: object `test.$(OBJEXT)' created both with libtool and without
Makefile.am:5: variable `libtest_a_LDFLAGS' is defined but no program or
Makefile.am:5: library has `libtest_a' as canonical name (possible typo)

Both of the errors should not occur, given the statements in "if ..." and
"else" are mutually exclusive and can't be run at the same time.
