I'll answer my own question:  NO!

gmake[3]: Leaving directory `/home/jerry/postgresql-7.4/contrib/spi'
/bin/sh ./pg_regress --temp-install --top-builddir=../../..
--schedule=./parallel_schedule --multibyte=SQL_ASCII
============== creating temporary installation        ==============

pg_regress: initdb failed
Examine ./log/initdb.log for the reason.

The initdb.log gave the exact same reason for failure, except for:
 "reduce PostgreSQL's consumption of semaphores by reducing its
max_connections parameter (currently 10)."

I know from the error msg in the RPM installation that even with a
'max_connections" = 1 the failure occurres.   It seems that the standard
MDK 9.2 kernel (2.4.22-10mdk) is not compatible with PostgreSQL 7.3.4 or
7.4.  ???
