translit() on Solaris 8 m4 1.4 et al seemed to have a bug I'm working
around, the resulting name of /dev/zero/ test was ac_cv_file__dv_zro.
Not healthy. translit() was original not intended for the abuse that
we provided it, so I'm doing-over with sed y, and not getting far enough.
The way the code is structured, leaving it as a config-time macro is fine
but resulting in a bogus expression...
echo "$ac_t""$ac_cv_file_$apr_safe" 1>&6
checking for /dev/zero... (cached) _dev_zero
It occurs to me WHY did we use APR_CHECK_FILE() instead of AC_CHECK_FILE()?
What does it buy us?
I'd rather just chuck crufty macros rather than 'fix' them, when it's
sufficiently covered already by autoconf.
My draft fix before I gave up on fixing looked like...
dnl APR_CHECK_FILE(filename); set ac_cv_file_filename to
dnl "yes" if 'filename' is readable, else "no".
AC_DEFUN([APR_CHECK_FILE], [
dnl Pick a safe variable name
apr_safe=`echo "$1" | sed 'y%./+-%__p_%'`
AC_CACHE_CHECK([for $1], [ac_cv_file_$apr_safe], [
if test -r $1; then
eval "ac_cv_file_$apr_safe=yes"
else
eval "ac_cv_file_$apr_safe=no"
fi])
])
