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

+++ b/src/interfaces/ecpg/include/meson.build

ecpg_conf_data.set('ENABLE_THREAD_SAFETY', 1)

foreach key : ecpg_conf_keys

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