Oliver, thank you for your answer.

But clang does recognize '-c' on Windows as it uses it to compile all
other files.

When I invoke b2.exe with "toolset=msvc-14.0", the command looks like this:

ml64 -nologo -c -Zp4 -Cp -Cx -DBOOST_ALL_NO_LIB=1
-DBOOST_CONTEXT_EXPORT= -DBOOST_CONTEXT_SOURCE -DBOOST_DISABLE_ASSERTS
-DNDEBUG -DBOOST_ALL_NO_LIB=1 -DBOOST_CONTEXT_EXPORT=
-DBOOST_CONTEXT_SOURCE -DBOOST_DISABLE_ASSERTS -DNDEBUG /W3  -Fo
"D:\path\to\boost\bin.v2\libs\context\build\msvc-14.0\release\address-model-64\link-static\runtime-link-static\threading-multi\asm\make_x86_64_ms_pe_masm.obj"
"D:\path\to\boost\libs\context\src\asm\make_x86_64_ms_pe_masm.asm"

But when "toolset=clang-win" the command becomes:

-c -Zp4 -Cp -Cx -DBOOST_ALL_NO_LIB=1 -DBOOST_CONTEXT_SOURCE
-DBOOST_DISABLE_ASSERTS -DNDEBUG -DBOOST_ALL_NO_LIB=1
-DBOOST_CONTEXT_SOURCE -DBOOST_DISABLE_ASSERTS -DNDEBUG /W3  -Fo
"D:\path\to\boost\bin.v2\libs\context\build\clang-vc14-win\release\link-static\runtime-link-static\threading-multi\asm\make_x86_64_ms_pe_gas.obj"
"D:\path\to\boost\libs\context\src\asm\make_x86_64_ms_pe_gas.asm"

I see two problems here:

1) BB does not know the name of assembler when clang-win is used;
2) BB tries to use command arguments from ml64.exe (all those -Zp4,
-Cp and -Fo belong to Microsoft Assembler) to compile gas source.
