Fwd: Issue with recursive includes, resource limits, and make-3.81?

[Garrett Cooper]

Trying out a recursive include, I seem to have run into a resource  
issue:

make[2]: Entering directory `/scratch/ltp-full-20080430/tools/apicmds
../Makefile.inc:4: ../Makefile.inc: Too many open files
make[2]: *** No rule to make target `all'.  Stop.

Running FC8 with a self-rolled copy of make-3.81. No patches or  
functional changes apart from a few debug lines.

What sections of the make code (i.e. which parts in read.c?) should I  
look into for solving this issue / finding "leaky filehandles", or is  
this a known issue?

Thanks,
