ecpg_config.h symbol missing with meson - Mailing list pgsql-hackers

I checked the generated ecpg_config.h with make and meson, and the meson 
one is missing

#define HAVE_LONG_LONG_INT 1

This is obviously quite uninteresting, since that is required by C99. 
But it would be more satisfactory if we didn't have discrepancies like 
that.  Note that we also kept ENABLE_THREAD_SAFETY in ecpg_config.h for 
compatibility.

Fixing this on the meson side would be like

diff --git a/src/interfaces/ecpg/include/meson.build 
b/src/interfaces/ecpg/include/meson.build
index 31610fef589..b85486acbea 100644

  foreach key : ecpg_conf_keys
    if cdata.has(key)

Alternatively, we could remove the symbol from the make side.
