Hi,
Since "major" windows update of march 2026 on W11 25H2 64b, I constat change about C library RTL 32b (like "crtdll.dll" stored in C:\Windows\SysWOW64).
I detect this because simple command "lcc -v" with LCC compiler 32b fail with error message Windows appear :
"... GetMainArgs unreachable ..."
I search with tool "lddw" (porting of ldd on Win32) directly to know what DLL is breaking, and listing stop after load of "crtdll.dll" (stored in usual directory C:\Windows\SysWOW64 in which all 32 bit DLL are stored on W11 64 bit).
I compare size of this DLL on my "old" configuration fix PC (resdtrict to W11 beginning version), and size are very different, and date is about 2021 ... not 2026. To try, I transfer this most size DLL in C:\Windows\SysWOW64 (after manipulations with my "double boot" W11/Linux on my laptop
), and ... YES, I resolve this problem.
"lcc -v" work again.
But, and I don't know why ..., Borland C/C++ 5.5.1 compiler fail too during use into CB :
cmd /c bcc32 | grep Borland

Happy, fail is reproductible
But, if I suppress only one space of this last command line before first option "-L...", linkage succeed :
ilink32.exe -q -aa -v -LC:\BCC55\lib\psdk -LC:\BCC55\lib c0w32 objBC55\Debug\src\Lesson03.obj,binBC55\Debug\Lesson03.exe,,import32.lib cw32mti.lib opengl32.lib glu32.lib gdi32.lib winmm.lib user32.lib kernel32.lib,,objBC55\Debug\src\Lesson03.res
Strange ? Not ? Call of " GetMainArgs" with old buggy DLL "crtdll.dll" ?
I know, it's not a behaviour about "faulty" CB, only system environment seem buggy ... but, just to test, can you suppress unnecessary spaces during generation of command lines ?
Here extract of my CB project with Borland C/C++ 5.5.1 :

Because in CB configuration, I have just add "-v" in Tab "Another linker options" without spaces ...
Thank's for all.
