recent gnulib has problems with read, write and close within structs

[Joël Krähemann]

Hi,

Because recent gnulib has problems with read, write and close as
struct fields. I am still using:

gnulib$ git log
commit 2d431ac35c4943a3655c07ba91870d2323321b43 (HEAD -> master,
origin/master, origin/HEAD)

Here is my code:

https://git.savannah.nongnu.org/cgit/gsequencer.git/tree/ags/object/ags_application_context.h#n112

Actually it fails here:

https://git.savannah.nongnu.org/cgit/gsequencer.git/tree/ags/X/ags_xorg_application_context.c#n431

Here is a snipped of the terminal output:
