BTW, lguide.ihp says that I may increment stack size by OPTION STACK,
but this option affects only .EXE format header. .COM files with and w/o
this option are equal. I found in cstart_t.obj mention for __stacksize, but
in cstrt086.asm I see that it valid only with "__TINY__", and this variable
not explained/mentioned anywhere else (not in *.h nor *.ihp).

Sorry, I found the trouble myself (explained in lguide.ihp) - wlink
searches wlink.lnk (only in) PATH! Now wlink works without LIB environment
variable and with "sys com" in command line.

...and 10116 for ATTRIB.COM. Of course - with same object file (in
small memory model) difference is only in .EXE header (64 bytes) and in
different startup modules (for .COM - cstart_t.obj; for .EXE comes from
clibs.lib?).
