I got following: gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wendif-labels -fno-strict-aliasing -I../../src/interfaces/libpq -I. -I../../src/include -D_GNU_SOURCE -c -o pgbench.o pgbench.c pgbench.c: In function `parseQuery': pgbench.c:1105: error: `var' undeclared (first use in this function) pgbench.c:1105: error: (Each undeclared identifier is reported only once pgbench.c:1105: error: for each function it appears in.) pgbench.c:1092: warning: unused variable `hvar' (note that the line number might be different what it should be in your work file since I have applied Yoshiyuki's patches in prior). The cause of this is obvious and easy to fix. However I wonder this is because of accidental old or wrong patches. Can you resubmit new patches against CVS Head? -- Tatsuo Ishii SRA OSS, Inc.
