For several weeks, I have been seeing the gcc 4.5 builds terminating in
libcpp with "cannot compute suffix of object files..."
In the configure.log, it starts complaining with
configure:2992 ..... "-V must come at the start of the command line" ...
"unrecognized option '-qversion'"...
"xgcc: no input files"
Maybe this means nothing, but:
The next step reports failure of the compile test for suffix.
When I attempt to repeat the compile command shown, it gives no
diagnostics, but sure enough the code returned to bash is 1.
If I run $HOME/libgcc/configure, it appears to configure OK, but when I
run make in libcpp, it fails eventually when attempting to build
addtf3.o (config/soft-fp/quad.h:63 error: unable to emulate 'TF'
So, the cygwin build has grown beyond my experience of how to work
around its quirks.
