OK, here we go:
cc -DHAVE_CONFIG_H -I. -I.. -I../lib -I.. -I../lib -I/usr/local/include -g
-E btowc.c> i.c shows (... denote empty lines):
#line 279 "/usr/local/Floss/sed-4.2.1/lib/../lib/stdint.h"
...
typedef int _verify_intmax_size[2 * (sizeof (gl_intmax_t) == sizeof
(gl_uintmax_t)) -
...
#line 62 "/usr/local/Floss/sed-4.2.1/lib/../lib/stdlib.h"
...
struct random_data
{
So apparently something is going wrong in stdint.h, it misses the "1];"
which is after a line break (i.e. after crah 80 in the terminal window).
That rings a bell, we have a "#pragma columns N", and /usr/include/stdint.h
(and other files in /usr/include too) for some stupid reason sets this to
80...
