161725 - update cygwin uname checks

Status: RESOLVED FIXED

Description

[hacker formerly known as [e-mail]]

When using cygwin's uname on w2k, OS_TARGET improperly gets set to
CYGWIN_NT-5.0.  It should be set to WINNT.

Set OS_TARGET when resetting OS_ARCH

This patch fixes the problem of not setting OS_TARGET whenever OS_ARCH is reset
for mks & cygwin.

The changes to nsprpub/configure.in are not
necessary.

The aren't necessary when building Mozilla as NSPR forces OS_TARGET to be WIN95
when --with-mozilla is set.  However, for the NSPR standalone builds, the wrong
value will be set and the various OS_TARGET tests in NSPR will not work as desired.

[Wan-Teh Chang]

For the NSPR standalone builds, these changes still
aren't necessary.  NSPR's configure script does some
things in a different order from Mozilla's configure
script.  Perhaps this is why Mozilla's configure
script needs these changes but NSPR's configure script
doesn't.

Just update mozilla's configure.in

Wan-Teh, you're right. I must've grepped the wrong autoconf.mk in my previous
test.	 I obviously need a vacation from my vacation. :-P  OS_TARGET isn't set
before the win32 detection in NSPR & LDAP so it falls down to the test -z
"$OS_TARGET" case and sets OS_TARGET=OS_ARCH.

Chris,  I think something like this would work for
mozilla/configure.in:

I also suspect that Mozilla's build system may not need
OS_TARGET at all; otherwise you won't be able to get
away with not setting OS_TARGET to WIN95 when you are
building on Windows NT/2000/XP.

Wan-Teh, that could work.  OS_TARGET needs to be set for win32 as we do have a
couple of checks for WINNT specific modules (under activex & installer). 
Hardcoding OS_TARGET was preferable to letting the users set random values for
OS_TARGET that may not be supported (like WIN98 & WINXP).  If we remove the
hardcoded values, we should add a check to make sure that OS_TARGET is set to
either WIN95 or WINNT if OS_ARCH=WINNT.

NSPR makes the distinction between WINNT and WIN95.
Mozilla only needs what NSPR calls WIN95.  This is
why I said Mozilla's build system may not need
OS_TARGET.

If you are building Mozilla with OS_TARGET=WINNT,
your definition of OS_TARGET is different from NSPR's.

Yes, it is slightly different.  Where NSPR uses OS_TARGET to replace generic
win32 code with NT-enhanced win32 code, Mozilla uses OS_TARGET to enable the
compilation of modules that use NT-enhanced code only.
