Re: [PATCH] fcntl-h: define O_CLOEXEC and O_EXEC if not defined; use new defines

[Bruno Haible]

Hi Paul,

> * lib/progreloc.c (find_executable): Use O_EXEC rather than O_RDONLY.

The lib/progreloc.c file is used by the modules 'relocatable-prog' and
'relocatable-prog-wrapper'. The latter module is careful to require no
.h file overrides from gnulib, as it would complicate the build process of
this module. So, this file cannot assume that O_EXEC is defined. I'm
adding this fix:

        relocatable-prog-wrapper: Fix compilation failure due to O_EXEC.
        * lib/progreloc.c (O_EXEC): Define fallback.
