At the very least there is insufficient quoting. The third
argument to AC_ARG_ENABLE should be quoted.
Here is part of what the (non-free) Autoconf manual says about
quoting:
----------------------------------------------------------------------
When calling macros that take arguments, there must not be any blank
space between the macro name and the open parenthesis. Arguments should
be enclosed within the M4 quote characters `[' and `]', and be
separated by commas. Any leading spaces in arguments are ignored,
unless they are quoted. You may safely leave out the quotes when the
argument is simple text, but _always_ quote complex arguments such as
other macro calls. This rule applies recursively for every macro call,
including macros called from other macros.
For instance:
AC_CHECK_HEADER([stdio.h],
[AC_DEFINE([HAVE_STDIO_H])],
[AC_MSG_ERROR([Sorry, can't do anything for you])])
is quoted properly. You may safely simplify its quotation to:
AC_CHECK_HEADER(stdio.h,
[AC_DEFINE(HAVE_STDIO_H)],
[AC_MSG_ERROR([Sorry, can't do anything for you])])
Notice that the argument of `AC_MSG_ERROR' is still quoted; otherwise,
its comma would have been interpreted as an argument separator.
The following example is wrong and dangerous, as it is underquoted:
AC_CHECK_HEADER(stdio.h,
AC_DEFINE(HAVE_STDIO_H),
AC_MSG_ERROR([Sorry, can't do anything for you]))
