Fedor Sergeev of Sun pointed out that my analysis of (bool) -0.5 as an
integer constant expression was incorrect, as the "-" isn't allowed in
C99. I installed this fix into gnulib and coreutils (and a similar
fix into autoconf).

You're right. I overloo

No
Hi,
The macro AC_HEADER_STDBOOL (in gnulib: in stdbool.m4, in autoconf-2.59c:
in headers.m4) rejects valid 'bool' implementations.
Seen with Sun C 5.9 ("c99 -Xa") for Linux/x86. The config.log contained:
configure:30747: checking for stdbool.h that conforms to C99
configure:30806: /opt/sun/compi
