[ECOS] SH Tool Building Problem (egcs-20000403 snapshot)

[John M. Mills]

I trying to build the eCos toolset for Hitachi SH processors under
WinNT/SP4, and failing with egcs-20000403.

I did fresh installations of Cygwin-B20.1 and gcc-2_95_2-cygb20.tar.gz. 

I built and installed binutils-000404 and added their (exec-prefix)/bin to
my path.

I configured for:
/c/usr/src/egcs-20000403/configure \
 --target=sh-elf --prefix=<blah> --exec-prefix=<blah>/<host> \
 --with-gnu-as --with-gnu-ld --with-newlib

'make -w all-gcc' fails with an internal compiler error while trying to
build 'tmplibgcc2.a'. The build log ends as follows:

Configuring for a i586-pc-cygwin host.

I got similar results with other snapshots. Does this look familiar to
anyone?
