Ciao Óscar,

AFAIK Angelo and others that build Emacs on MSYS2 are not using
the PKGBUILD, but following the recipe on the Emacs' docs (possibly with
their own personal modifications.)
really, I DO build Emacs on MSYS2 with that _PKGBUILD_ [*]. It is on
GNU/Linux and on OSX which I use some other recipe (my build scripts..)
Regarding the image.c.diff and lread.c.diff patches...
If I remember correctly, when the mingw*imagemagick port is installed,
'configure' tries to "build" using the imagemagick support and the build
fails if those patches are not applied.. Maybe the patches fix the build
with imagemagick support. But is it a real support or only a workaround
so that the build is completed, apparently adding the support for
imagemagick?
I have this doubt..
Ciao,
Angelo.
