Could you please annotate this with explanations of how/why this is supposed to work correctly? I have trouble following the convoluted logic, perhaps because I don't know enough about Autoconf. (I also don't know what results you expect from "test -x foo.exe" when foo.exe is an empty file produced by "touch foo.exe".) > Another way to fix the problem is to adopt the solution used by autoconf: > make sure that the variable $ac_executable_extensions, which is set in > config.site on some platforms, gets substituted: > > AC_SUBST(ac_executable_extensions) > > and put the following to texi2dvi.in: > > for dir in $PATH; do > for exec_ext in '' @ac_executable_extensions@; do > if test -f "$dir/$1" && test -x "$dir/$1"; then > ... I'm okay with this method, provided that ac_executable_extensions can be computed reliably (you didn't say how). -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
