Subject: [PATCH] Update const-var openmp const-var handling
|
||||
|
||||
OpenMP 4.0 dropped the data-sharing rule that predetermined const-vars
|
||||
as "shared". GCC implemented this rule change with GCC-9. Because of
|
||||
the rule change, libimagequant fails to build with gcc-9.1.0. This
|
||||
patch updates the code so that it is conformant with OpenMP 4.0 rules.
