I just double-checked and it still builds fine on Git for Windows (as
expected).

The reason it seems to have worked before, too, is that somehow -lcrypto
does not require gdi32.dll here. As a matter of fact, we do not link with
gdi32 at all:

$ printf 'include Makefile\nprint:\n\t@%s\n\t@%s\n\t@%s\n' \
	'echo all: $(ALL_LDFLAGS)' \
	'echo libs: $(LIBS)' \
	'echo imap: $(IMAP_SEND_LDFLAGS)' |
  make -f - print

all: -Wl,--nxcompat -Wl,--dynamicbase -Wl,--pic-executable,-e,mainCRTStartup
libs: libgit.a xdiff/lib.a git.res -lws2_32 -lntdll -lpcre -lz -liconv -lintl -lcrypto
imap: -lcurl -lssl -lcrypto -lcrypto

It is a bit curious that -lws2_32 *does* only show up in $(LIBS), but I
guess it is simply the fact that we use a newer GCC (gcc.exe (Rev2, Built
by MSYS2 project) 6.2.0) that allows Git for Windows to be built even
without this patch.

In any case, it does not break things, and it helps Cygwin, so: ACK

Ciao,
Dscho

P.S.: I pushed this to Git for Windows' `master`, too:
