#146 plConfig.h define macro conflicts

[bicatali]

plConfig.h.in contains:

#ifdef HAVE_CONFIG_H
#  include <plplot_config.h>
#endif

However plplot_config.h does not get installed.

Other software such as Gnu Data Language, are including plConfig.h and have defined the HAVE_CONFIG_H macro internally to their build system, since it is the standard autotools and usually cmake way. It results in error building GDL, as exemplified in:

https://bugs.gentoo.org/show_bug.cgi?id=503076

Would it be possible to use another macro?

Thanks for reporting this nameclash issue. I have now fixed that in the svn trunk version of PLplot by changing HAVE_CONFIG_H to PLPLOT_HAVE_CONFIG_H everywhere in our source tree. That fix will go into our next release.
