windres fails to do a round-trip compile.


Cross compiling on linux fails:

x86_64-w64-mingw32-windres -J res -i CascView.res -O rc -o cascview_patch.rc
x86_64-w64-mingw32-windres -J rc -i cascview_patch.rc -O res -o
cascview_patch.res
x86_64-w64-mingw32-windres: cascview_patch.rc:68: syntax error
x86_64-w64-mingw32-windres: preprocessing failed.

Native compile on windows fails too:
D:\cascview2>windres -J res -i CascView.res -O rc -o cascview_patch.rc

D:\cascview2>windres -J rc -i cascview_patch.rc -O res -o cascview_patch.res
windres: cascview_patch.rc:76: syntax error
cascview_patch.rc:1: fatal error: when writing output to : Invalid argument
    1 |
      |
compilation terminated.
windres: preprocessing failed.


Can we fix it asap? Because I need this to write paper for my ph.d program.
