Phil,

Use my patches first (URL below), then build it as following:

  
  $ <srcdir>/configure --prefix=/Cygnus/cygwin-b20 \
    --exec-prefix=/Cygnus/cygwin-b20/H-i586-cygwin32 \
    -v i586-cygwin32
  
  $ make bootstrap > make.log 2>&1

When it builds, just install it elsewhere:
  
  $ make prefix=/home/EGCS --exec-prefix=/home/EGCS/H-i586-cygwin32 \
    install
  
The H-* bit is strictly not necessary. 

The other, and the correct one IMO, as what others suggested. Mount
everything so that /usr is correct and then everything just works.

* patches at 
  ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygwin/snapshots/

The gcc-2.95-relative-path.diff is a really nice feature that allows
completey relocatable trees. That's how I build my distributions.

Some of these patches may already be integrated in the snapshots, so
please check the ChangeLogs (or deal with the patch errors/complaints).

Regards,
Mumit
