could you please review this tiny fix which merely renames some
variable names to make them C/C++ standard conformant and prevent a
name clash with a macro defined in in /usr/include/iso/ctype_iso.h on


C/C++ forbid variable names which begin with an underscore followed by
a capital letter.

The C++ Standard [ISO/IEC 14882-2003], Section specifies
the following sets of reserved names: "Each name that contains a
double underscore __ or begins with an underscore followed by an
uppercase letter is reserved to the implementation for any use."

The C99 Standard [ISO/IEC 9899:1999] specifies in section 7.1.3 the
following sets of reserved names: "All identifiers that begin with an
underscore and either an uppercase letter or another underscore are
always reserved for any use."

sun/java2d/loops/ProcessPath.c defines the variable names "_X" and
"_X" where "_X" clashes with the preprocessor macro:

#define _X      0x00000080      /* heXadecimal digit */

defined in /usr/include/iso/ctype_iso.h on Solaris.

Thank you and best regards,
