Hi Taco,

__attribute__ is also used in at least these files:

texk/web2c/luatexdir/tex/errors.w
texk/web2c/luatexdir/pdf/pdfgen.w
texk/web2c/luatexdir/utils/utils.w
texk/web2c/luatexdir/font/writefont.w
texk/web2c/luatexdir/font/writet1.w
texk/web2c/synctexdir/synctex.c

which, during the build, are used to generate the files in Work/texk/web2c/:

errors.c
pdfgen.c
synctex-pdf.c
synctex-xe.c
utils.c
writefont.c
writet1.c

Taco, could you please look at the luatex-relates files? and maybe
someone would also patch synctex.c.

Best,
v.
