8 ## Please note: AIX does NOT have library versioning per se (there is no 'SONAME' capability).

9 ## So, we are using 'windows' style library names, that is, libicuuc20.1.so instead of libicuuc.so.20.1

11 # When building stubdata, special considerations need to be made when building on AIX with GCC

12 BUILD_HOST_ICU=AIX_GCC

14 # Certain files don't compile in -ansi mode (e.g. umutex.c, toolutil.c, and cdatatst.c)
