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],[i.za...@gmail.com]) 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 :()
