Ciao Ken,

(In reply to Ken Brown from comment #12)
> There are still problems with merged resources.  Namely, the resulting
> executable after being stripped won't run, at least in some circumstances. 
> Here's a simple test case on 64-bit Cygwin with the just-released binutils-
> 2.24.51-3.  It uses the attachments test.c, emacs.rc, and
> default-manifest.rc.
> 
> 1. Compile the three source files:
> 
>   $ gcc -c test.c
>   $ windres -o emacs.o emacs.rc

when I try this I get :(

windres: impossibile aprire file "emacs-x64.manifest": No such file or
directory


i.e. "cannot open emacs-x64.manifest> No such file..."


indeed

$ head emacs.rc
1 24 "emacs-x64.manifest"

#ifndef VS_VERSION_INFO
#define VS_VERSION_INFO 1
#endif

VS_VERSION_INFO VERSIONINFO
 FILEVERSION 24,3,50,0
 PRODUCTVERSION 24,3,50,0
 FILEFLAGSMASK 0x3FL


Ciao,
Angelo.
