bootstrap: Fix some windows issues [PR 98300]
When breaking out the sample server from the gcc/cp directory, it lost its check for mmap, and the sample resolver just assumed it was there. Fixed thusly. The non-mapping paths in module.cc weren't (recently) excercised, and led to a signedness warning. Finally I'd missed c++tools's config.h.in in the gcc_update script. There I took the opportunity of adding a 'tools' segment of the dependency lists. PR bootstrap/98300 contrib/ * gcc_update: Add c++tools/config.h.in. c++tools/ * configure.ac: Check for sys/mman.h. * resolver.cc: Don't assume mmap, O_CLOEXEC are available. Use xmalloc. * config.h.in: Regenerated. * configure: Regenerated. gcc/cp/ * module.cc: Fix ::read, ::write result signedness comparisons.
