You say that you was succesful with C, so... But there's something
I spend nice time with: all mingw32 distributions up to egcs 1.1
produce broken nonrelocatable dll's (more precisely, there
workability fase-of-moon dependent: I saw relocatable dlls produced, I
saw dlls which don't load at all). I haven't tried egcs 1.1.1 yet, but
I don't think problem's gone: bug is in the bfd, probably in its like
to use past-eof seeks to align sections (ms leaves previous data
there, though that region supposed to be zeroed). Cygnus reported
workaround for this in b20, and since cygwin linker produces correct
dlls, but cygwin strip still f%#@%$ up them %) So: try to use latest
cygwin ld instead of mingw32's.
