So we have:
extern wint_t __btowc_alias (int __c) __asm ("btowc");
extern __inline wint_t
__attribute__ ((__nothrow__)) btowc (int __c)
{ return (__builtin_constant_p (__c) && __c >= '\0' && __c <= '\x7f'
? (wint_

Works for me. The preprocessed source is certainly not what was compiled
(I assume the linkage specification of btowc was actually different).
Working testcase, robustened against -std=c99:
extern int __btowc_alia

Yes, it was. But I apologize, the invocation needs to include -std=gnu99 to
observe the problem, e.g., gcc -std=gnu99 -O2 conftest.i. Withou

If so, then you are using too old glibc headers with -std=gnu99, without
fixincludes and without -fgnu89-inline. Only headers of glibc later than
mid-2007 are prepared for -std=gnu99 with GCC 4.3 without fixincludes a
