building in object directory

[Jay A. St. Pierre]

On Solaris 8, if I try to do this:

  tar xvzf gawk-3.1.1.tar.gz
  mkdir gawk-3.1.1-obj
  cd gawk-3.1.1-obj
  ../gawk-3.1.1/configure --src=../gawk-3.1.1
  make

The build fails because it can't find custom.h:

make 'CFLAGS=-g -O2' 'LDFLAGS=' all-recursive
make[1]: Entering directory `/appl/sde/src/gnu/gnu-src/gawk-3.1.1-obj'
Making all in intl
make[2]: Entering directory `/appl/sde/src/gnu/gnu-src/gawk-3.1.1-obj/intl'

-DIN_LIBINTL -DHAVE_CONFIG_H -I.. -I. -I../../gawk-3.1.1/intl  -g -O2  
../../gawk-3.1.1/intl/intl-compat.c

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/appl/sde/src/gnu/gnu-src/gawk-3.1.1-obj'
make: *** [all] Error 2

I was able to correct this by changing the intl/Makefile.in to 
add -I$(top_srcdir) to the variable INCLUDES (see diff below).  I 
don't know if this is the "right" way to fix it, but it works.
