So enhance the + search list capabilities with an optional symbol how the wrapped + function is named internally. Also hack the parser so "stat" gets + actually probed and not mistaken for __xstat. + + Using "realstat" as a symbol is not the best choice as it might be + confusing, but "statstat" seemed even worse. + +--- a/configure.ac ++++ b/configure.ac +@@ -353,9 +353,13 @@ + + :>fakerootconfig.h.tmp + +-for SEARCH in %stat f%stat l%stat f%statat %stat64 f%stat64 l%stat64 f%statat64 %mknod %mknodat; do +- FUNC=`echo $SEARCH|sed -e 's/.*%//'` ++for SEARCH in %stat s%tat@realstat f%stat l%stat f%statat %stat64 f%stat64 l%stat64 f%statat64 %mknod %mknodat; do ++ FUNC=`echo $SEARCH|sed -e 's/.*%// ; s/@.*//'` + PRE=`echo $SEARCH|sed -e 's/%.*//'` ++ SYMBOL=`echo $SEARCH|sed -e 's/.*@//'` ++ if test "$SYMBOL" = "$SEARCH" ; then ++ SYMBOL="${PRE}${FUNC}" ++ fi + FOUND= + for WRAPPED in __${PRE}x${FUNC} _${PRE}x${FUNC} __${PRE}${FUNC}13 ${PRE}${FUNC}; do + AC_CHECK_FUNCS($WRAPPED,FOUND=$WRAPPED) +@@ -366,8 +370,8 @@ + dnl for WRAPPED in _${PRE}${FUNC}; do + dnl FOUND=$WRAPPED + if test -n "$FOUND"; then +- PF=[`echo ${PRE}${FUNC}| tr '[a-z]' '[A-Z]'`] +- DEFINE_WRAP=[`echo wrap_${PRE}${FUNC}| tr '[a-z]' '[A-Z]'`] ++ PF=[`echo $SYMBOL | tr '[a-z]' '[A-Z]'`] ++ DEFINE_WRAP=[`echo wrap_${SYMBOL}| tr '[a-z]' '[A-Z]'`] + DEFINE_NEXT=[`echo wrap_${FOUND}| tr '[a-z]' '[A-Z]'`] + DEFINE_ARG=[`echo wrap_${FOUND}| tr '[a-z]' '[A-Z]'`] + AC_DEFINE_UNQUOTED(WRAP_${PF}, $FOUND) +@@ -509,6 +513,12 @@ + #define TMP_STAT __astat + #define NEXT_STAT_NOARG next___astat + ++#define WRAP_REALSTAT __astat ++#define WRAP_REALSTAT_QUOTE __astat ++#define WRAP_REALSTAT_RAW __astat ++#define TMP_REALSTAT __astat ++#define NEXT_REALSTAT_NOARG next___astat ++ + #define WRAP_LSTAT_QUOTE __astat + #define WRAP_LSTAT __astat + #define WRAP_LSTAT_RAW __astat |
