Hello, here is a small webrev removing the 2 mentioned options .
When compiling jdk/jdk on AIX (using current xlc16 / xlclang) we run into these warnings :
warning: 1540-5200 The option "langlvl=c99vla" is not supported. : This option controls variable length arrays / Enables or disables support for C99-type variable length arrays. warning: 1540-5200 The option "langlvl=noredefmac" is not supported. : Controls whether a macro can be redefined without a prior #undef or undefine() statement.
see https://www.ibm.com/support/knowledgecenter/SSGH3R_16.1.0/com.ibm. compilers.aix.doc/compiler.pdf
The mentioned options are only available with the legacy xlc (non xlclang). I propose to remove these options, because xlc16 / xlclang is now the default compiler.

Thanks and best regards, Matthias
I think this is fine for 14.
Cheers, Thomas

The 2 options seem to be gone with the current xlc16 / xlclang++ . I would like to remove them - any objections ? (removing them might be bad for older xlc versions but I think we probably cannot compile with older versions any more ) .
