gnustep-back XGFont.m problem

[Dennis Leeuw]

gnustep-back produces an error:
XGFont.m: In function `-[XGFontInfo(Private) xCharStructForGlyph:]':
XGFont.m:360: `enc' undeclared (first use in this function)
XGFont.m:360: (Each undeclared identifier is reported only once
XGFont.m:360: for each function it appears in.)
XGFont.m:360: warning: passing arg 3 of `GSFromUnicode' from

one error I could solve:

line 361:
misses a ; like this:
          index = c;

But then it went way beyond my knowledge:

XGFont.m: In function `-[XGFontInfo(Private) xCharStructForGlyph:]':
XGFont.m:360: `enc' undeclared (first use in this function)
XGFont.m:360: (Each undeclared identifier is reported only once
