Michael, please read
http://wiki.lazarus.freepascal.org/libc_unit#The_problem_with_unit_libc,
so you know what you are talking about and understand the difference
between library libc and unit libc.
I do know, but anyway while it does make sense to use some functions
from libc, there might be others that maybe better are done in the RTL
without accessing the libc equivalent.
Thread support _might_ be a candidate, as threadvar access could be
improved (but maybe it could be improved even without dropping the
threadlib binding). OTOH threadlib automatically provides FUTEX access
for archs that provide it.
OTOH, on archs like the different ARM flavors, the RTL implementation of
"atomic" functions is not perfect.here using or looking at libc might
lead to an improvement, as same automatically uses the appropriate
Kernel-helper-functions or the advanced hardware instructions if
available in the sub-arch without the need of recompiling the project.
