Hi Irena:

I have now changed the style of plplot_parameters.h to replace one huge string
literal by a large number of small string literals that the compiler
should automatically concatenate together.

I prefer this new style on general principles, and gcc compiles this
style just as well as the old style. It's possible your Portland Group
compiler will still choke on this style as it attempts to concatenate
those string literals together. But on the other hand, it might work.

To test that possibility, please try the latest version of our
source code using

git clone git://git.code.sf.net/p/plplot/plplot plplot.git

Then try your normal build (with -DENABLE_tcl=ON or else by removing
-DENABLE_tcl=OFF from the cmake command line since ENABLE_tcl is ON by
default) referring to this version of the source tree rather than
5.10.0 and starting from an empty build tree. If your compiler is
able to compile bindings/tcl/tclAPI.c without issues, then the change in style
should be judged a success.

Furthermore, I hope your set of Portland Group compilers is able to
finish the rest of a default build of PLplot without issues, but if
there are such issues we will try to deal with them since we prefer to
have PLplot builds be successful on all compilers and not just gcc.

By the way, I think the above is the first reference to our new
official git repository on this list (although there has been a large
amount of traffic about this huge change in PLplot development on the
plplot-devel list).  The short story is our svn repository at SF is
now frozen in read-only mode and as of a few days ago we switched to
using git for PLplot development with the above being our official git
repo.  I am pretty much a git newbie myself, but my use of it for the
last several days shows it is an extremely popular version control
system for good reasons.  Therefore, I think there is an excellent
chance this change from subversion to git will not only help our
current set of developers but also attract new developers to the
project.
