PostgresSQL on QNX 4

--------------------

PosgresSQL 6.5.2 could be ported to QNX 4.25.

This port is an important step because PostgreSQL is now the only free

The most effort required the emulation of System V semaphore sets,

A lot of make files had to be changed because $(LD) doesn't support the
|

-r option on QNX 4.
|
||||
|

It is recomended to use the GNU C compiler instead of the Watcom compiler

Make problems:
|
||||
--------------
|
||||
|
||||
Sometimes the Watcom library manager wlib crashes with SIGSEGV on some
|
||||
object files. This is a general problem and not PostgreSQL related.
|
||||
Currently bootstrap.o causes such a crash. The workaround is not to include
|
||||
the object file into the SUBSYS.o but link it directly. For further information
|
||||
see backend/Makefile and backend/bootstrap/Makefile.
|
||||
libpgsql.a currently cannot be generated because of the same problem. But this
|
||||
doesn't matter since shared libraries are not supported.
|
||||
|
||||
Currently yacc fails on interfaces/ecpg/preproc/preproc.y because of
|
||||
exceeded maximum table size. You can generate the preproc.h and preproc.c
|
||||
files on another platform and use them. This is only a problem when you use
|
||||
the current source tree since preproc.h and preporc.c are included in official
|
||||
distributions.
