| Does something like
|
| for ac_func in LIST
| do
| ...
| ac_tr_func=HAVE_`echo $ac_func | tr '[a-z]' '[A-Z]'`
| AC_DEFINE_UNQUOTED($ac_tr_func, 1, [ /* Define if you have $ac_func. */])
| ...
| done
|
| work now, too?
No: you have to use literals. config.h is extracted by m4, which
cannot read shell variables. The only way out is
AC_DEFINE_UNQUOTED(AC_TR_CPP([HAVE_$1]), 1,
[ /* Define if you have $ac_func. */])
and *never* use a sh-for loop. m4 loops are ok, but no sh loop.
