please don't remove cygwin test releases too early

[Denis Excoffier]

Hello,

Today i was using cygwin-3.7.0-0.266… (found under /x86_64/release/cygwin, installed also the corresponding cygwin-doc and cygwin-devel) 
and built the new GCC 15.2.0. Then i built many (about 100) GNU or not-so-GNU software with no errors at all until i found in tcl-9.0.2 
that GCC returns with status 2 (i.e. not 0, not 1, not 4) for compilation of tclStubLib.o (and compilation fails). Similarly, same 
return code (2) with fastcwd.o (and others, fastcwd is the first one) under winsup/cygwin/x86_64.

Same with GCC 15.1.0. But this was surely not the case when i installed GCC 15.1.0 in April.
Same with cygwin-3.7.0-0.277… (the more recent one).

But not the same with cygwin-3.7.0-0.124... that i fetched on the 6th of June. In this case, compilation is ok (i checked with tcl only, not fastcwd.o).

Then i started to bisect between cygwin-3.7.0-0.124… and cygwin-3.7.0-0.277…

Unfortunately, cygwin-3.7.0 revisions from -124 to -246 are gone!

Please don’t remove cygwin test releases too early.

Thank you.

Regards,
Denis Excoffier.
