[Bug-indent] indent-2.2.9: build failure on Apple Darwin 6.3 (MacOS 10.2.3)

[Nelson H. F. Beebe]

indent-2.2.9 failed to build on Apple Darwin 6.3 (MacOS 10.2.3):

gcc -DHAVE_CONFIG_H -I. -I. -I..   -I/usr/local/include  -g -O2 -c `test -f
'texinfo2man.c' || echo './'`texinfo2man.c
texinfo2man.c:2:20: malloc.h: No such file or directory

The fix was simple: add -Isys to CFLAGS.  This is the ONLY
system among the 15 or so different UNIX systems I work on
where malloc.h is stored in /usr/include/sys/malloc.h.
