Subject: Re:  macro past '##' behaving differently that prev. and other
 C/C++ compilers


Please, Additional Questions re-guarding the error msg and processing.  (
as noted in the bug report 12531 )

Note again that the macros and paste actions are properly being processed
and the preprocessor output is complete with the include properly expanded.
ONLY the error message, error code, and therefore the suppressed
object/link is the problem.
      If I then 'gcc foo.i' from the gcc output  with -save-temps option, I
get my object/linked program OK.

Based on the statement below that this was changed with the 3.0 release;
      I must wonder why GCC 3.2.1 released with Free BSD does not exhibit
this behavior?
      Nor does GCC 3.1 on Apple Mac OSX exhibit it either?

I am only seeing this occur on selected Linux OS's using GCC 3.+  ( two
RedHat Intel GCC 3.2.2/GCC 3.3 , and one SuSe intel GCC 3.3.1)
      not on GCC 3.2.1 or 3.1 in other Linux environments.

Could you explain further?

Thank you.

Jerry A Williams

Look at bug 10212 (which has the c++ standard part, C++98 [cpp.concat]/3)
and bug 10829 and
other bugs.  This was changed in the 3.0 release of gcc anyway, which was
released two years ago.
