The macros ‘SHLIB_OPENMP_CFLAGS’ etc can be set in e.g. ‘config.site’.
This is needed for ‘clang’ 3.7.0 which needs a compiler option for

The macros ‘SHLIB_OPENMP_CFLAGS’ etc can be set in e.g. ‘config.site’.
‘configure’ now supports the OpenMP flags ‘-fopenmp=libomp’ (clang) and ‘-qopenmp’ (Intel C).
Various OpenMP macros can be set to override the default behaviour of ‘configure’: see file ‘config.site’.
‘nchar(x, "w")’ assumed -1 for characters it did not know about (e.g. zero-width spaces): it now assumes 1 (and knows about zero-width characters).
