hsc2hs does not fail

2002-04-16 Thread Axel Simon 

Hi,

for some reason hsc2hs does not fail if the automatically generated
program fails to execute. This only happends if I forget to set
LD_LIBRARY_PATH before saying make. But it leads to a confusing error
messages when an empty .hs file is left and ghc complaints with "file name
does not match module name".

The patch below was done against ghc-5.02.2 on FreeBSD.

Cheers,
Axel.
