[Mesa-dev] [PATCH] glsl: try again to fix PRIx64 / MinGW build problem

[Brian Paul]

inttypes.h doesn't always define the PRIx64 macro when compiling C++
code with MinGW.  For that case, simply define PRIx64 to be "lx".
This generates a format/argument type mismatch warning.  And using
"llx" generates other warnings.  Just live with it.
