this part broke the Solaris build:
ld: fatal: libstdc++-symbols.ver-sun: 7568: symbol
'_ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE19_M_create_and_placeEjj':
symbol version conflict
ld: fatal: libstdc++-symbols.ver-sun: 7570: symbol
'_ZNSt7__cxx1112basic_stringIwSt11char_traitsIwESaIwEE19_M_create_and_placeEjj':
symbol version conflict
Both symbols are matched in GLIBCXX_3.4.21 and GLIBCXX_3.4.36:
##_ZNSt7__cxx1112basic_stringI[cw]St11char_traitsI[cw]ESaI[cw]EE1[68-9]*
(glob)
##_ZNSt7__cxx1112basic_stringI[cw]St11char_traitsI[cw]ESaI[cw]EE*_M_create_*
(glob)
Changing the first to
##_ZNSt7__cxx1112basic_stringI[cw]St11char_traitsI[cw]ESaI[cw]EE1[68]*
(glob)
(i.e. omitting 9 from the final char set) allows the build to continue.
