I downloaded a fresh copy of aRts-1.5.10 and do a configure && make.  Everything 
was fine.  Doing a grep on the source shows that 'PATH_MAX' come up in


If I do

g++ -DHAVE_CONFIG_H -I. -I.. -I../mcop -I../artsc -I../mcop -I../mcop -I../flow 
-I../flow -DEXECUTE=\"/usr/local/kde/bin/artsd\" -I/usr/local/kde/include 
-I/opt/qt/include -I/usr/X11R6/include  -I../libltdl  -DQT_THREAD_SUPPORT 
-D_REENTRANT -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include 
-Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align 
-Wchar-subscripts -Wall -W -Wpointer-arith -O2 -Wformat-security 
-Wmissing-format-attribute -Wno-non-virtual-dtor -fno-exceptions -fno-check-new 
-fno-common  -ftemplate-depth-99  -MT artsplay.o -MD -MP -MF .deps/artsplay.Tpo 
-E -o artsplay.E

and look at artsplay.E, I see that PATH_MAX is replaced by 4096.  My conclusion 
is that it is in one of the system include files, but I don't know which one.

Tracing the include files, I see:

and in
  #define PATH_MAX        4096  /* # chars in a path name including nul */

It sounds like you didn't install the linux headers.  See LFS 6.7.
