It is essentially right, but not totally. You have two problems:
underquoted (and your configure will not run), and missing description
for the CPP symbols you define (and autoheader will die).
To solve the quotation problem, do this:
AC_CHECK_FUNC(seteuid,
[AC_DEFINE(HAVE_SETEUID, 1)],
[AC_MSG_ERROR([This program re quires that seteuid be available])])
to solve the CPP problem, either give the description (3rd arg to
AC_DEFINE), or better yet, use AC_CHECK_FUNCS (See the doc):
AC_CHECK_FUNCS(seteuid, [],
[AC_MSG_ERROR([This program re quires that seteuid be available])])
