Bug ID: 101779
Summary: Compilation of rust-demangle.c fails on MinGW
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: demangler
Assignee: unassigned at gcc dot gnu.org
Reporter: eliz at gnu dot org
Target Milestone: ---
The version of rust-demangle.c included with Binutils 2.37 doesn't
compile with MinGW:
mingw32-gcc -c -DHAVE_CONFIG_H -O2 -gdwarf-4 -g3 -I.
-I../../binutils-2.37/libiberty/../include -W -Wall -Wwrite-strings
-Wc++-compat -Wstrict-prototypes -Wshadow=local -pedantic -D_GNU_SOURCE

^~~~~~~~~~~~~~~~~~~~~~~
This is because the data type 'uint' is not defined in the MinGW
headers. I used uint32_t instead, and it compiled OK.
