Sun Studio 12 Update 1's brain will melt on these two occurances of
using "goto" to jump into a loop. It'll emit these warnings:
"read-cache.c", line 761: warning: statement not reached (E_STATEMENT_NOT_REACHED)
"xdiff/xutils.c", line 194: warning: statement not reached (E_STATEMENT_NOT_REACHED)
Suppress these warnings by using a Sun Studio specific pragma
directive to turn them off, but only do so if __sun is defined, which
is the macro Sun Studio uses to identify itself under both its C and
C++ variants, see http://developers.sun.com/sunstudio/products/faqs/cpp.html
