Ouch, my mistake. kpse-cxx-hack, as originally designed for texk/*/ requires
AC_CANONOCAL_HOST but doesn't say so since that is automatically provided by
kpse-common.m4 used in texk/*/configure.ac. Later kpse-cxx-hack was also
used for teckit_compile from libs/teckit/.
Could you please run a quick test (assuming the you have used the ./Build
rm -rf texk/lcdf-typetools
This should configure and build lcdf-typetools, this time linking the C++
runtime library statically. Please tell if this works result.
In the meantime I'll fix kpse-cxx-hack.m4.
