RE: Template Member Function Compilation Error on Solaris


Yes, this makes sense.  By definition, all identifiers starting with an
underscore or containing two consecutive underscores are reserved for
the compiler.  You should avoid using such identifiers.

Subject: Re: Template Member Function Compilation Error on Solaris

Never mind. I identified the problem. Solaris defines _L, _S, etc.
macros in some libc header files.  So the _L, _S in my code was
replaced with some constants after preprocessing. This is a legacy
problem with Solaris library, not the code.
Same problem exists for ports of cygwin, and possibly OS X.
