System: FreeBSD hand.dotat.at 4.5-STABLE-20020220 FreeBSD 4.5-STABLE-20020220 #15: Wed Feb 20 07:46:52 GMT 2002 fanf@hand.dotat.at:/FreeBSD/obj/FreeBSD/releng4/sys/SHARP i386
>Description:
In environments where the system headers are aware of the compilation
environment that the program desires, using gcc -ansi may disable all
the Unix definitions, which is rather unhelpful for flag settings
intended for Unix programs.
>How-To-Repeat:
Try compiling with $BDECFLAGS a program that uses functions like asprintf().
On Linux (for example) this fails because asprintf() is in the C standard.
>Fix:
Index: make.conf
