Re: Location to specify C compiler option in C extension

Hi Tom,

PG_CPPFLAGS ought to work.  One point is that you need to set that before
including pgxs.mk; maybe it's an ordering problem?

On closer inspection, it was working, but the pg Makefile was specifically including “-Wdeclaration-after-statement” which I think was overriding the ‘-std=c99’ part. The line below fixed the problem.

PG_CPPFLAGS += -std=c99 -Wno-declaration-after-statement

Thanks, sorry for the noise.
