I use the GNU C compiler:
lam-7.1.1> gcc --version
gcc (GCC) 3.4.1
with options:
lam-7.1.1> printenv CFLAGS
-Wall -std=c99 -pedantic -O3
The problem appears to be that
lam-7.1.1> cat /usr/include/signal.h
.
.
.
#ifdef __USE_POSIX
.
.
.
# include <bits/siginfo.h>
.
.
.
# endif
.
.
.
the signal.h header file will *not* include the bits/siginfo.h
header file unless __USE_POSIX is defined
but my GNU C compiler will *not* allow __USE_POSIX
to be defined when i use the -std=c99 option.
