Some typo in the sources showing up on Solaris 2.6 only?

Why do you think there is a typo? O_RDWR is a valid constant that should
be provided on all Unix-like systems.

Can you please find out from the open(2) man page: a) whether Solaris
2.6 supports the O_RDWR constant, b) what header files to include, and
c) whether including these header files solves the problem?

So adding these two lines helped:

# diff /usr/scratch/Python-2.5.2/Modules/mmapmodule.c.ori
> #include <sys/types.h>
> #include <fcntl.h>

survey of other modules that use O_RDRW
The following include sys/type.h and fcntl.h unconditionally:
  bsdmodule.c, dbmmoudle.c, _fileio.c

posixmodule.c includes them after doing an #ifdef check

mmapmodule.c currently (2.7 trunk) includes sys/types.h with an ifdef
check, but fcntl.h not at all.

Still a problem with 2.7 or later?

Compilation works on Solaris 10 and 11 for quite some time. Please reopen the bug report if you still have issues.
