C++Builder 12.3 first build [bcc32 Warning] processthreadsapi.h(1165): W8026 Functions with exception specifications are not expanded inline

[alank2 5]

3 questions:

 

#1 - If I open a project and build it, I get 7 of this warning:

[bcc32 Warning] processthreadsapi.h(1165): W8026 Functions with exception specifications are not expanded inline

 

If I build it again, they disappear.

If I close the project (not the IDE), reopen it, build again, I get the 7 warnings back for the first time, but again, not subsequent times.

 

#2 - Another oddity, the build window shows 50 warnings.  It is really the 7 warnings apparently counting at 7 each for a total of 49 plus the 1 other warning that is always present.  Why not just 8 warnings?

 

#3 - The last warning (which doesn't go away no matter how many times I build is):

[bcc32 Warning] System.Net.URLClient.hpp(772): W8058 Cannot create pre-compiled header: code in header

Is this something Embarcadero needs to fix in System.Net.URLClient.hpp?

Precompiled header being compiled only 1 time?

Is it perhaps 7 messages for 7 different translation units (.cpp files) that are using the same header?  Each translation unit is compiled independently, so output messages are not consolidated across TUs.

What does line 772 actually look like?

>Precompiled header being compiled only 1 time?

 

I've never had a build produce different messages before even with precompiled headers.

It is the last line of this:

[bcc32 Warning] processthreadsapi.h(1165): W8026 Functions with exception specifications are not expanded inline

What does line 1165 of processthreadsapi.h look like?  I don't see ANY exception specifications in my copy of processthreadsapi.h, but I'm using 12.2 and not 12.3.

It is the last line of this:

On the closing '};' of the class?

 

I don't see anything that would be considered "code in header" to trip up a precompiled header, unless the compiler is complaining about the static const members.

Highlighted here:

Exactly.

 

>I don't see anything that would be considered "code in header" to trip up a precompiled header, unless the compiler is complaining about the static const members.

 

Could it be these?

   static _DELPHI_CONST System::Word DefaultConnectionTimeout = System::Word(0xea60);
    
    static _DELPHI_CONST System::Word DefaultSendTimeout = System::Word(0xea60);
    
    static _DELPHI_CONST System::Word DefaultResponseTimeout = System::Word(0xea60);
