Linux/Alpha provides the following useful/relavent symbols:
linux
__alpha
__alpha__
__linux
__linux__

I had gone through the pgsql 6.2.1 source trying to fix/replace
all instances of 'linuxalpha' and such used as defines with '(defined
__alpha__) && (defined __linux__)'. But I hit a few snags in testing (i.e.
lack of time), and by the time I got things about sorted out, 6.3 came out
and changed so much I need to go through again and do it all anew. The
baisc problem it looks like you hit as well, is that non-standard define
names were used, and then never included in the platform specific defines.
This was the reason Linux/Alpha couldn't even get initdb to run (probably
same for you). Of course, the regression tests are still not perfect, and
there is a good deal of cleanup on the Linux/Alpha end of things as well.
It will be a while, but things are moving.
