   Modified Files:
           pkgsrc/mail/imap-uw: Makefile distinfo
           pkgsrc/mail/imap-uw/patches: patch-ab

   Log Message:
   Use "soc" target if building with Sun Studio C++ and modify that target
   to use "cc" rather than an absolute path (which is no longer correct).
   This fixes the build with that compiler without breaking the build
   using GCC.
