(I wrote the above patch.) The trick is that AC_CHECK_PROG contains the following code: for ac_exec_ext in '' $ac_executable_extensions; do if AS_EXECUTABLE_P(["$as_dir/$ac_word$ac_exec_ext"]); then thus we eventually get to test -f tex.exe && test -x tex.exe which succeeds. > Therefore, "test -x tex" was modified to check for > `tex.exe' if `tex' does not exist. Using `test -x' alone has always the danger that you encounter a directory. Perhaps texi2dvi could use test -x tex && ! test -d tex (Autoconf couldn't use this because of possible portability fears.)
