Re: Problem configuring pspp-0.10.0 on Linux Slackware 14.1

[Frans Houweling]

Ehm ... I'm afraid I am on the wrong list. I did try to modify this line 
in configure:
> ac_compile='$CC -c $CFLAGS $CPPFLAGS CFLAGS+=" 
-std=c11"conftest.$ac_ext >&5'
into
> ac_compile='$CC -c $CFLAGS $CPPFLAGS -fgnu89-inline CFLAGS+=" 
-std=c11"conftest.$ac_ext >&5'
to no avail.
What is the correct way to add flags to CC?
Thanks, frans
