Re: [PORTS] Port Bug Report: syntax errors in spinlocks (s_lock.h)

Jarda, I have used PostgreSQL on Digital Unix for a long time, and have
never seen the problem you are reporting.

I am using 4.0d (patchkit 2 applied).

I have used it since the 6.0 days. Now I am running the latest 6.4 CVS
source, but have been running 6.4 and 6.4.2.

DEC C V5.6-075 here.

DEC 2000 AXP 300, uname -a: OSF1 haddock.euitt.upm.es V4.0 878 alpha

Which version? I use 3.75.

I *never* saw this error before. I can send my the output from configure
and gmake, if you want.

>> GCC:
>> ../../../include/storage/s_lock.h: In function `tas':
>> In file included from buf_init.c:29:

I haven't tried gcc 2.8 (2.7 didn't work).

I would think so. Please repeat the build on a clean source tree.

You mean gmake, don't you? Or have you replaced the system's make?
