[Gm2] make failure on cygwin (strsignal)

[Chris Lilley]

Hello ,

I attempted to install the stable release of gm2 in my cygwin
environment (previously I had been using gm2 under Kubuntu linux, with
precompiled binaries and apt-get install; here I was compiling from
source).

configure went ok (some warnings about zlib and other libraries,
although those warnings did not seem to get logged anywhere) and make
worked fine for some hours :) then halted because flex was required
and not present.

Added flex (and bison, in case) and generally updated cygwin to the
latest versions of everything.

Second attempt worked fine for some time then halted on conflicting
types for strsignal.

Not sure what to do next, if some dependency is missing or what. Here
is the end of the console output:
