I'm trying to build v2.03 gcc423s.zip/gcc423s2.zip natively on x86 XP.
(You know, build old/stable stuff should be a good step toward building new/current stuff..)

I see this in the "sub configure" of gcc/build-i386-pc-msdosdjgpp/fixincludes and libiberty.

If I cd into these directories and run configure manually, it finds /dev/env/DJDIR/bin/grep ok.

I also see a few like this:

c:/djgpp/src/gcc/423/libcpp/configure: redirection error: Bad file descriptor (E
BADF)

but it doesn't seem fatal.

I'll dig in more later -- in particular change it to echo more and see what it tries and gets.

I suspect for some reason it runs out of memory trying long lines, and "unwrapping" it by running configure directly, instead of within make, gives it more memory.

Maybe the line length it looks for should be reduced???? (I realize this would probably be an unpopular upstream patch..)

(Btw, installing Cygwin to the root of a drive somehow interferes with djgpp. I never figured out why, but something about Perl and carriage returns (ie: \r)..the problem shows up trying to build autoconf 2.57. Perhaps Cygwin Perl was ahead in the path or something..)
