This is NSS with a Cmake Buildsyste To compile a static NSS library for Windows we've used the Chromium-NSS fork and added a Cmake buildsystem to compile it statically for Windows. See README.chromium for chromium changes and README.trustbridge for our modifications.

17 ** Win16 stdio special case.
18 ** To get stdio to work for Win16, all calls to printf() and related
19 ** things must be called from the environment of the .EXE; calls to
20 ** printf() from the .DLL send output to the bit-bucket.
21 **
22 ** To make sure that PR_fprintf(), and related functions, work correctly,
23 ** the actual stream I/O to stdout, stderr, stdin must be done in the
24 ** .EXE. To do this, a hack is placed in _MD_Write() such that the
25 ** fd for stdio handles results in a call to the .EXE.
26 **
27 ** file w16stdio.c contains the functions that get called from NSPR
28 ** to do the actual I/O. w16stdio.o must be statically linked with
29 ** any application needing stdio for Win16.
30 **
31 ** The address of these functions must be made available to the .DLL
32 ** so he can call back to the .EXE. To do this, function
33 ** PR_MD_RegisterW16StdioCallbacks() is called from the .EXE.
34 ** The arguments are the functions defined in w16stdio.c
35 ** At runtime, MD_Write() calls the registered functions, if any
36 ** were registered.
37 **
38 ** prinit.h contains a macro PR_STDIO_INIT() that calls the registration
39 ** function for Win16; For other platforms, the macro is a No-Op.
40 **
41 ** Note that stdio is not operational at all on Win16 GUI applications.
42 ** This special case exists to provide stdio capability from the NSPR
43 ** .DLL for command line applications only. NSPR's test cases are
44 ** almost exclusively command line applications.
45 **
46 ** See also: w16io.c, w16stdio.c
