Hi Tom,

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.
