RE: [Bug bootstrap] [4.1 regression] Build fails on Cygwin

[THOMAS Paul Richard 169137]

Thanks Francois-Xavier,

I saw your message and assumed that Cygwin was in the same state.  I looked
for but did not see the

+ #undef  COMMON_ASM_OP
+ #define COMMON_ASM_OP	"\t.comm\t"

in the patches.  It's strange, I was searching on COMMON_ASM_OP; perhaps
fingers trouble.

Re: [Bug bootstrap] [4.1 regression] Build fails on Cygwin

[François-Xavier Coudert]

Patches needed to build on mingw32 include
http://gcc.gnu.org/ml/gcc-patches/2005-08/msg00009.html and
http://gcc.gnu.org/ml/gcc-patches/2005-08/msg00097.html . The first
one contains the fix to your problem, the second one is the latest
version of the patch to fix dllimport.

However, on mingw32, this is not enough to build (see PR 23210, for example).

[Bug bootstrap] [4.1 regression] Build fails on Cygwin

[THOMAS Paul Richard 169137]

In spite of chanting the incantations given in PR 21766, both a simple make
and a bootstrap fail on Cygwin, with

gcc -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissin
g-prototypes -Wmissing-format-attribute -fno-common   -DHAVE_CONFIG_H    -I.
-I.

COMMON_ASM_OP is defined for other systems but not for i386/winnt.
