Looking at the configure log on gharial, the only incorrect symbol
seems to be PG_VERSION_NUM:

#define PG_MAJORVERSION "13"
#define PG_MAJORVERSION_NUM 13
#define PG_MINORVERSION_NUM 0
#define PG_VERSION "13devel"
#define PG_VERSION_STR "PostgreSQL 13devel on ia64-hp-hpux11.31, compiled by gcc (GCC) 4.6.0, 64-bit"
#define PG_VERSION_NUM

which squares with the compile error that's being thrown (it's pointing at
a macro that uses PG_VERSION_NUM).

I'd suggest reverting the change in how PG_VERSION_NUM is computed
in configure.in --- that was certainly not necessary to the patch,
and evidently you're falling foul of some weird behavior around
nesting double-quotes and backquotes.
