Это опции не того линкера который в freecommandline лежит. Не от ilink32, а от tlink32. Вот что такое -ax я честно говоря не знаю, а остальные вот:


/x
The Off option tells the linker not to create a map file.

/Tpd
TLINK32 generates a 32-bit protected-mode Windows .DLL file.

/d 16-bit, /wdpl 32-bit
When the Warn Duplicate Symbols option is on, the linker warns you if a symbol appears in more than one object or library files.
If the symbol must be included in the program, the linker uses the symbol definition from the first file it encounters with the symbol definition.
Use the TLINK32 command-line option /w-dpl to turn this warning off.

-tWDE
This option is the same as Windows DLL, All Functions Exportable except that only _ _far functions marked with the _export keyword (and methods of classes marked as _export) are given the extra prolog/epilog. This is far more efficient than the “Windows DLL, All Functions Exportable” option since only those functions called from outside the module get the prolog overhead. This option requires determining which functions or classes need to be exported in advance. No .DEF file manipulation is needed.
The -WDE command-line option is supported for backward compatibility, and is equivalent to -tWDE.
