[parted-devel] [PATCH] build: mark functions with const attribute, per gcc warnings

[Rudi Heitbaum]

fixes warning since glibc-2.43

For ISO C23, the functions wcschr that return pointers into their
input arrays now have definitions as macros that return a pointer
to a const-qualified type when the input argument is a pointer to a
const-qualified type.

../../parted/strlist.c: In function 'wchar_strchr':
../../parted/strlist.c:61:16: warning: return discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
   61 |         return wcschr (str, ch);
      |                ^~~~~~
