I'm getting (somewhat) reasonable error messages with 19980517 and the same
with 19980508 (in run from latest drivers) on sparc-sun-solaris2.5.1:

 vonbrand@pincoya$ gcc err.c 
 err.c:1: parse error before `xp_unabs'
 err.c: In function `xp_unabs':
 err.c:4: parse error before `{'
 err.c: At top level:
 err.c:8: parse error before `return'
 vonbrand@pincoya$ g++ err.c 
 err.c:1: syntax error before `('
 err.c:4: `base' was not declared in this scope
 err.c:4: warning: ANSI C++ forbids declaration `whil' with no type
 err.c:4: syntax error before `{'
 err.c:6: warning: ANSI C++ forbids declaration `' with no type
 err.c:6: abstract declarator `int' used as declaration
 err.c:6: `base' was not declared in this scope
 err.c:7: parse error before `}'
