A fix for clashing "bool" typedefs

For compilers which do not have the built-in bool type, BaBar created a typedef equating bool to char. The RogueWave STL (which is the default implementation on BaBar platforms, except OSF1) solved the same problem by using typedef bool int. The two typedefs cannot coexist in an executable.

The OSF1 cxx and HP-UX aCC compilers have built-in bool type, and so there should be no clash between the BaBar typedef and the STL's typedef (neither typedef is used).
On Solaris and AIX: There is a work-around now available for testing. Basically, we replaced RogueWave's STL's bool typedef with the BaBar one, and recompiled the accompanying RogueWave library. We chose this solution, rather than changing the BaBar typedef to int, because there would be problems of function signatures being confused if we now changed from char to int.

The patched versions have been tested (to some extent) on Solaris and minimally on AIX. They are now the defaults (from SoftRelTools V00-06-78 onward).

For another site to implement this, you must modify stdcomp.h in the RogueWave include directory, copy the BaBarBool.hh file to that directory, and recompile the standard library. (Of course, RogueWave code is proprietary; you must have purchased a license to get it. The following is intended to illustrate how to do the modifications at other licensed sites.)

• The bool typedef (in BaBarBool.hh) used can be found in the BaBar package, V00-05-00.
• [updated 11/11/98] The modified piece of stdcomp.h file for Solaris can be seen here
  At SLAC, the Sun include directory is
  $BFROOT/package/RogueWave/708/workspaces/SOLARIS26/SUNPRO42/15s/include
  The recompiled library is ../lib/libstd15s.a (this is a multithreaded version).
• The modified piece stdcomp.h file for AIX can be seen here
  At SLAC, the AIX include directory is $BFROOT/package/RogueWave/testSTL703/stdlib/include. The recompiled library is ../lib/libstdns.a ("not shared" version), along with a standard RogueWave link (libstd.a). This is RogueWave version 7.0.3.
