Description
The project settings can add too many include file search paths (/i) onto the tasm32 command line.  When this fails to build the object file, it fails silently.  The output from tasm32 is the normal help screen.  The linker will eventually fail when it needs something that was in the assembler files.

A simple (non-sense) project has been created and will be attached.  Several worthless include file path items have been added to reach the error.

Steps to Reproduce:
1) Create project with C++ source file with inline assembly language code.

2) Have numerous items in the project include file path option.

3) Compile to failure.  In the detailed build output, the tasm32 help screen can be seen where it should instead be assembling.
Workarounds
Remove items from the include file path list until it compiles.

The issue seems to not be the number of include file paths, but the total length of the tasm32 command parameters.  I had one project where the assembly files outputted were left as basename.o instead of basename.obj.  Removing one item from the include path to shorten the command and the obj file is generated with the correct name.

This may be what is also happening with the older report # 58149.
