ee-gcc.exe: installation problem, cannot exec `<snip>/cpp.exe': Invalid argument

[mkst]

When trying to use wibo to replace wine, the command fails when trying to call cpp.exe.

Running under wibo:

I'm not sure what's going wrong. It is able to read the specs file which sits alongside the cpp.exe binary (although the log suggests that wine fully expands the path).

Edit:

Running cpp.exe manually via wibo works:

$ ~/github/wibo/build/wibo cpp.exe -E test.c 
# 1 "test.c"
int foobar(char x) {
  return 123;
}

OK, it's due to the backslashes. The command decomp.me wants to execute is like this:

~/github/wibo/build/wibo backend/compilers/ps2/ee-gcc2.95.2-273a/lib/gcc-lib/ee/2.95.2/cpp.exe -lang-c -v -I Z:\backend\compilers\ps2\ee-gcc2.95.2-273a\bin\..\lib/gcc-lib/ee\2.95.2\ -isystem /backend/compilers/ps2/ee-gcc2.95.2-273a/lib/gcc-lib/ee/2.95.2/include -D__GNUC__=2 -D__GNUC_MINOR__=95 -Dmips -DMIPSEL -DR5900 -D_mips -D_MIPSEL -D_R5900 -D__mips__ -D__MIPSEL__ -D__R5900__ -D___mips__ -D_MIPSEL -D_R5900 -D__mips -D__MIPSEL -D__R5900 -D___mips -D__OPTIMIZE__ -D__LANGUAGE_C -D_LANGUAGE_C -DLANGUAGE_C -D__SIZE_TYPE__=unsigned -D__PTRDIFF_TYPE__=int -D__LONG_MAX__=9223372036854775807L -U__mips -D__mips=3 -D__mips64 -D__mips_eabi -D__mips_single_float test.c /tmp\ccbaaaaa.i

but swapping out \ for / works:

~/github/wibo/build/wibo backend/compilers/ps2/ee-gcc2.95.2-273a/lib/gcc-lib/ee/2.95.2/cpp.exe -lang-c -v -I Z:/backend/compilers/ps2/ee-gcc2.95.2-273a/bin/../lib/gcc-lib/ee/2.95.2/ -isystem /backend/compilers/ps2/ee-gcc2.95.2-273a/lib/gcc-lib/ee/2.95.2/include -D__GNUC__=2 -D__GNUC_MINOR__=95 -Dmips -DMIPSEL -DR5900 -D_mips -D_MIPSEL -D_R5900 -D__mips__ -D__MIPSEL__ -D__R5900__ -D___mips__ -D_MIPSEL -D_R5900 -D__mips -D__MIPSEL -D__R5900 -D___mips -D__OPTIMIZE__ -D__LANGUAGE_C -D_LANGUAGE_C -DLANGUAGE_C -D__SIZE_TYPE__=unsigned -D__PTRDIFF_TYPE__=int -D__LONG_MAX__=9223372036854775807L -U__mips -D__mips=3 -D__mips64 -D__mips_eabi -D__mips_single_float test.c /tmp/ccbaaaaa.i

I feel like a blind 'find-replace' of \ to / is going to be lead to issues, but I dont know what the right way to solve this is? a heuristic to guess if a string containing \ is a path?

Further testing, it's these two arguments that are breaking the command:

1. The final backslash here Z:\backend\compilers\ps2\ee-gcc2.95.2-273a\bin..\lib/gcc-lib/ee\2.95.2\
2. The backslash in the output filename /tmp\ccbaaaaa.i

So a potential fix could be to replace all \ if the string contains any /?

Using main the command works, but still not right in decomp.me CI, will investigate.
