[PATCH] Fix cross compilation with wine for the case SHELL != bash.

[Alexei Sheplyakov]

Hello!

I've tried to cross compile the GMP (http://gmplib.org) library using libtool
version 2.2.7a (from current git). The compilation went fine, however, the test
suite failed due to GMP dll being not found:

$ make -C tests check
make[2]: Entering directory 
`/home/pc7135/varg/tmp/build/woe32/gmp/gmp-4.2.4-build/tests'
err:module:import_dll Library libgmp-3.dll (which is needed by 
L"Z:\\home\\pc7135\\varg\\tmp\\build\\woe32\\gmp\\gmp-4.2.4-build\\tests\\.libs\\t-bswap.exe")
 not found

The patch below fixes this issue:

Subject: [PATCH] Fix cross compilation with wine for the case SHELL != bash.

Some shells' builtin `echo' command behaves as prescribed by POSIX, that is,
it always interprets escape sequences such as '\v', '\b', etc. Since backslash
is a path separator, that's not what we want (think of "Z:\home\varg\bin").
That's why func_to_host_path should use $ECHO instead of echo, otherwise
(woe32) paths get mangled.
