APA> This problem does not occur in 21.2-b33 native NT either. APA> It is still present in 21.1.10 native NT though, which I am currently APA> building with XEBUG_XEMACS=1. I found the lisp code causing the problem in Windows NT native XEmacs, but can't figure out why. Please help! compile.el has this: (defvar grep-find-use-xargs (if (equal (call-process "find" nil nil nil grep-null-device "-print0") 0) 'gnu) "Whether \\[grep-find] uses the `xargs' utility by default. If nil, it uses `grep -exec'; if `gnu', it uses `find -print0' and `xargs -0'; if not nil and not `gnu', it uses `find -print' and `xargs'. This variable's value takes effect when `compile.el' is loaded by influencing the default value for the variable `grep-find-command'.") On vanilla Windows NT with a vanilla XEmacs native build C:\Winnt\system32\find.exe gets called and reports following error: FIND: Parameter format not correct So I moved C:\Winnt\system32\find.exe out of the way and promptly my installation of cygwin find.exe was used instead. Alas, this does not fix the problem. I still get the end-of-file error during (require 'compile) and don't know how to debug it any further. Best regards, Adrian APA> OK, the end-of-file error as shown in the CallStack below. APA> How can I find out where we are in compile.el (I have renamed APA> compile.elc to compile.elc.orig) when this happens?
