Message:

o Rewrote the libcXXXX.dll install rule to not play with emxload since

emxload sticks around when first loaded.

o Made unsetenv() cause tzset reload just like putenv() and setenv().
o Changed putenv() behaviour for removal (no '=' in input) to be identical

to unsetenv(). This solves duplicate variable testcase.

o Changed filestreams opened for both reading and writing to switch

more willingly between read and write mode.

o Made sscan() return EOF on EOF.
o Made sscan() skip blanks in input for '%%'.
o Implemented the stdio_unlocked stuff with BSD and GLIBC extension.

TODO: Require a new locktype which support recursive usage! Currently

a hack using 8 free flag bits is used.

o Corrected realpath() behaviour to return the path up to the failure

point on error. _realrealpath() also does this now.
(This also saves us a temp buffer and a copy of the result.)

o Fixed a bug in the handling of ".." in the path resolver.
o Extended that path resolver to check the directoryness of the input

according to flags and any trailing slashes.

o Change the path resolver to be very strict about UNC - UNC have exactly

two slashes at the start of the path.
