Follow up question on single threading

["Schlesinger, Philip" <ps...@filenet.com>]

Hi!  Using the Xerces single-threading rules as a model, we tried the
following changes in an attempt to force Xalan to build itself
single-threaded.  Do you think they're ok?  Would you have any
suggestions?

- Phil

         For Aix
o       Replace xlc_r and xlC_r libraries with xlc and xlC respectively
o       Replace makeC++SharedLib_r with makeC++SharedLib
o       Remove flag -D_THREAD_SAFE, add flag -DAPP_NO_THREADS
o       Grep -i thread Makefile*, remove all mentioning of thread, se
ignorecase, (Remove qthreaded, pthread)


-         For HPUX and HP Itanium
o       Add flag -DAPP_NO_THREADS
o       Remove inclusion of -lpthread 
o       Remove threading define like -D_PTHREADS_DRAFTS, -DXML_USE_DCE

We tried similar steps in Solaris, but got an error when compiling
XalanEXSLDateTime.cpp:

-         For Solaris 
o       Remove flag -D_REENTRANT , add flag -DAPP_NO_THREADS
o       Remove compiler switch -mt
o       Remove inclusion of -lpthread 

"/PEBuilds/bldtogether/xml-xalan/c/src/xalanc/XalanEXSLT/XalanEXSLTDateT
ime.cpp", line 188: Error: The function "localtime_r" must have a
prototype.
"/PEBuilds/bldtogether/xml-xalan/c/src/xalanc/XalanEXSLT/XalanEXSLTDateT
ime.cpp", line 194: Error: The function "gmtime_r" must have a
prototype.
(it seems to require the define of XALAN_NO_REENTRANT_TIME_FUNCTIONS to
see this method)

Those changes look fine, although you don't need to define APP_NO_THREADS 
for Xalan-C's sake.

Yes, you'll need to define XALAN_NO_REENTRANT_TIME_FUNCTIONS.
