[ECOS] ecos-CVS and GCC-3.0: Take 2-OK but for minor problems

[Richard Chan]

HOst i686-linux-pc-gnu
GCC 3.0 --disable-shared --enable-shared=libstdc++
Binutils 2.11.2

Folks, the host tools build with the following caveats

[1] tcl_inc_dir sets -I/usr/include explicitly on the c++ command line; this 
breaks #include_next in some of the libstdc++-v3 headers
which cannot find <string.h>

FIXME: (autoconf gurus???) if tcl_inc_dir is a system include path
to not add it to INCLUDES. Wow - never thought #include_next would
bite.

[2] Some files like interp.cxx flags.cxx cannot find prototypes
for the ctype.h functions.

FIXME: these files need to #include <ctype.h> somewhere
either cdlconfig.h or flags.hxx

The ecos and GCC-3 saga continues...that's all for now!
