Hi list!

I'v got a problem with recently released autoconf 2.64 (and even more
fresh 2.65).
Smth has changed since release 2.63 where the following code works
well (minimal example to reproduce the problem):


AC_PREREQ(2.63)

AC_INIT([check_headers_test],[0.0.1],address@hidden)

m4_include(check-headers.m4)
AC_CHECK_HEADERS([USED_C_HEADERS_LIST],,AC_MSG_ERROR([You need to have
the libc and system headers installed]))


external file (check-headers.m4) in real project is generated by
special target in Makefile and looks like:

dnl C header files:
m4_define([USED_C_HEADERS_LIST], [fcntl.h float.h memory.h math.h
stdio.h stdlib.h assert.h])

generated code looks like totally invalid :()
