iohann.s.titov@gmail.com Ivan S. Titov Local fork of ::gentoo sci-libs/pgplot-5.2.2-r9 to add -std=gnu89 in src_configure. ::gentoo's ebuild builds with the compiler default, which on gcc 16 (-std=gnu23) rejects K&R prototypes in drivers/figdisp_comm.c. Drop the -r99 once ::gentoo lands an equivalent fix.
