If you call
AC_FOO(...,
[something
AM_WHATEVER
...
])
where AM_WHATEVER requires AC_PROG_CC_C_O, then AC_PROG_CC_C_O will be
expanded before the beginning of AC_FOO.
AC_REQUIRED macros are expanded before the outermost AC_DEFUNed macro.
This means that the following won't work:
AC_FOO(...,
[something
AC_PROG_CC
AM_WHATEVER
...
])
You have to do
AC_PROG_CC
AC_FOO(...,
[something
AM_WHATEVER
...
])
Does it help?
Of course, this is just a guess. Post your configure.ac, if the guess
is not right.
Have a nice day,
Stepan Kasal
