#143 cannot compile under mingw

[Querino]

i get errors when i try to compile it under mingw.

first, i got a "qprintf.o:qprintf.c:(.text+0x6f): undefined reference to 'GifErrorString'"

i "fixed" that one, now i'm stuck at "libgif.a: error adding symbols: Archive has no index; run ranlib to add one"

now i give up.

btw, the " horrible old autoconf build system" always worked fine...

[Querino]

nevermind, got it somehow working under cygwin

The GifErrorString error is still there...

Using MSYS2/MinGW gcc 13.2.0 Updated the old patch from v5.2.1 to 5.2.2 and added it here.

[Eric S. Raymond]

I can't accept this patch. it breaks generration of .so files.

Can you ship a conditionalized verrsion that detects mingw and does the right thing withour disturbing the GCC 10 build?
